• 1-3: Bug fixes, including improperly applied moving spread values. Separated moving and not moving scoring.

1. Recoil is compensated for vertically.
   
2. You fire the weapon at its listed RPM - this is will therefore underrate the hidden spread decrease bonuses of Factory, Optical, and Marksman variants, so be aware.
   
3. You fire the weapon until you achieve a kill, and then reset spread and recoil while finding your next target.
   
4. Bullet velocity is considered at each range.
   
5. ADS firing, 50% moving and 50% not moving.
   
6. Recoil is tracked during every tick at a rate of 30 Hz using the recoil decrease equations and scaling updated during TSNP.

1. The Autoloading 8 .35 Marksman and Factory are the kings of TTK under 47 m (no surprises there). They show up on every list and even compete with bullpup-mod weapons in moving stances. They are followed by the Selbstadler 1906 Optical Factory and Sniper (>47 m). The Fedorov Avtomat (<27 m), Cei-Rigotti Optical (<37 m), and RSC Optical (<47 m) boast excellent effective TTKs within their ideal ranges.
   
2. The Selbstlader 1916 has a lousy TTK at all ranges, but it can handle standing and shooting at long range by virtue of capacity alone. The M1907 and Autoloading 8 .25 Extended have lousy effective TTKs over 27 and 17 m, respectively. I really cannot recommend the M1907 in any possible way.
   
3. The C96 Trench would be the worst SLR of the Medic class. That said, it is middle-of-the-pack out to its first drop off point at 22 m by virtue of its massive magazine and better-than-S1916 TTK. I think when its BTK is reduced with the TTK balancing patch, this weapon will be a legitimate option. Right now, while it is fun and at least defensible to use, it's awfully outclassed. The M1903 Experimental, however, is the absolute worst semi-automatic primary weapon by far. While the C96 Trench was at least comparable to the bottom tier composite scores, the M1903 Experimental was well below. Hopefully it gets some love in with the TTK pass. I have also added the Slugs from Assault and the Trench Carbines from Scout for reference - the 1900 Slug is quite good. The Carcano M91 is excellent over ~50 m as a heavy SLR.
   
4. Recommendations for long range (47+ m): Selbstlader 1906 Factory (#5 overall) for speed and versatility and the Selbstlader 1916 Optical (#7 overall) for bullets. If the S1906 is a scalpel, the S1916 is a cudgel; the 1916 just has enough bullets to survive recoil and spread patterns to secure kills by brute force. The Mondragons are a compromise, but they end up just being good at...nothing. At least the Selb. 1906 has the versatility to compete at closer ranges where the S1916 is worst-in-class.
   NOTE: Even though the General Lius are here, I cannot recommend them over the Selbstlader 1906. The single extra bullet stops mattering over 20 m because it becomes incredibly difficult to secure 2 kills per reload over that distance even when not moving. Furthermore, the improved accuracy of the Selb. 1906 means that while you have 1 fewer bullet, you on average land more shots per reload with the 1906 starting around 30 m (see Storm variant comparison figure for details).
   
5. Recommendations for mid-range (27-47 m): Autoloading 8 .35s (#1a,b overall), Cei-Rigotti Optical (#3 overall), and the RSC Optical (#6 overall) give you quick effective TTKs. The Farquhar-Hill Optical appears as a jack-of-all-trades option (#4 overall).
   
6. Recommendation for close quarters (0-25 m): Fedorov Avtomat Optical (#2 overall) shines here. Excellent moving characteristics and outclasses the Trench variant unless you never ADS. The Autoloading 8 .35s fair quite well here too.
   
7. Recommendation for extreme close quarters (0-15 m): Autoloading 8 .25 Extended (<17 m) for speed and ease of use if you really really need an edge at point-blank range. It is a straight upgrade from all M1907 variants (17-27 m you should be using the Fedorov Avtomat Optical anyway).
   
8. Best jack-of-all-trades weapons: Cei-Rigotti Optical (#3 overall) performs admirably at all ranges even after its damage drop off - note that it nearly competes with the Mondragons (C-R has less recoil and bullpup moving spread) and Gen. Lius (C-R has less recoil, better min. spread, and bullpup moving spread) even after its damage model becomes inferior. The only real drawback is its reload animation, which cannot be cancelled and resumed. The Farqhuar-Hill Optical (#4 overall) scores like a Selb. 1916 merged with a C-R Optical; the Optical spread characteristics and low horizontal recoil make this an underrated option with careful play (i.e. don't rush into point-blank fights).
   
9. A note on the interplay between Storm and Optical/Factory variants: If your horizontal recoil is high enough (0.5+ L + R), Storm variants will benefit you. If your recoil is less than that, Storm variants hurt more than they help. This is a MAJOR change from the pre-TSNP recoil scaling, and I personally didn't catch it until now. Bottom line here: General Liu Storm is good to use if that is your cup of tea, but the Farquhar-Hill or Mondragon Storm will cost you dearly, because their recoil is already small relative to the rest of its class. Personally, I don't like Storm variants because I like to fire at the optimal RoF given a weapon's SIPS, but these data show if you are planning on spamming a bit, the General Liu Storm variants can help you. See figures for these data.
   
10. A note on why Optical variants dominate the standings: Optical variants have improvement to both standing and moving spread, and that appears to be a massive advantage. When standing, Optical variants already have excellent hit rater values compared to other variants, and then when you tack on their moving spread buff, you end up with Optical variants dominating the standings. It seems to me that there is really no reason not to take advantage of Optical variants with: (1) excellent min. spread, (2) excellent SIPS, and (3) excellent moving min. spread. For the Cei-Rigotti and Fedorov Avtomat, the combination of the bullpup mod only makes this more obvious in terms of moving spread.
    
11. A note on the TTK shift: The TTK shift will buff high RoF weapons more than low RoF weapons. I anticipate all of the top-tier weapons will remain mainstays post-patch, but I expect the Cei-Rigotti to benefit the most in practice (with single fire at optimal rate vs. fully automatic Fedorov at max rate, unless you can click/pull the trigger at 416 RPM consistently). I expect the Selb. 1916 and the RSC to get dinged a bit in the rankings. See SLR Optimal RoF Analysis - TT Edition.
    
12. My personal choices:
    
    • Autoloading 8 .35 Factory on smaller game modes or on claustrophobic maps (e.g. Amiens, town on St. Quentin's Scar, trenches in Nivelle Nights, parts of Argonne Forest).
      
    • Cei-Rigotti Optical is in my regular rotation on smaller maps, and I anticipate it being a top-tier weapon post-TTK patch when its range is increased.
      
    • Farquhar-Hill Optical on open maps (all the In the Name of the Tsar maps, Monte Grappa, Ballroom Blitz, Sinai, Suez, etc.)
      
    • Fedorov Avtomat Optical when I need to be constantly on the move with a squad in CQC.

I'm a little surprised at this result, because I am thinking back to BF3 and the debate about using the foregrip (an attachment that reduced horizontal recoil, but increased min spread). It was the consensus that heavy barrel + foregrip was the way to go on most weapons as the higher starting (less accurate) min spread value was offset by the reduction in horizontal recoil. So, your with the HB+FG setup, your first shot was a little less accurate (but accurate enough), but the foregrip reduction in horizontal recoil makes up this difference in accuracy by the 3rd, 4th, and so bullet in a burst.

But for BF1, it seems that because optical variant conjoins both lower min spread AND lower SIPS that this produces better accuracy than just reducing horizontal recoil. But, optical gives you a flat (one time) 25% less min spread AND a per bullet 37.5% less SIPS whereas the storm variant gives a per bullet 40% less horizontal recoil. So, since the storm's variant has a bigger per bullet buff (40% versus 37.5%) does it ever catch up in accuracy over more bullets in a burst (does its per bullet difference make up for the initial lower min spread ever)? It might take too many bullets to make up the difference for it matter in practice where your accuracy is so poor anyway that it doesn't matter.

Question: How are the first shots for both variants not a 100% hit at 30m? There is no recoil involved and base spread is low enough that it does not matter at that range.
