Have done a rewrite and update on the sam spreadsheet. Added R2/R15 Mikinaak gear, and allowed splitting subjobs/food/etc between set 1 and set 2.
I set up the two gear sets to check out the conditions again, leaving them mostly identical aside from the body/hands/feet. Target is Delve Fodder, since that was one of the samples used for ccl's comparison.
Changing to Usu feet+Usu body capped haste for that set, so both sets are at 90.1 delay, negating that difference.
As I was going through and reapplying buffs to make sure they were the same, there was a pretty constant 17 DPS difference in Portus's favor until I added Minuets. Checking, it seems the Portus build's higher attack (53 att lead for Porthos/Phorcys/Whirlpool compared to Usu/Kari/Usu, after accounting for Berserk/Chaos) gave it a bit of an edge up until attack is capped. Once attack is capped, the difference narrows to just 3 DPS (still in Porthos's favor, though).
Next was a change in food. Double minuets puts you far enough past attack cap that RCBs do very little for you. With all the buffs, you'd still be capped even without any food at all; the only gain is from the str. So I tried swapping to the suggested Carbonara.
Porthos: 1170.935 => 1170.978
Usukane: 1167.604 => 1165.291
For the porthos build, there's no change. For the Usukane build, total damage actually drops. This is where things get tricky -- how much is gained and lost with changes like these depends on subtle variances from exact multi-attack rate (and thus average number of rounds per weaponskill), Save TP, and Store TP values. Finding the exact point where things might tilt in favor of one build or the other (assuming there are actual tipping points) can be difficult.
One such difference was the realization that I had Hunter's Roll on, not Samurai Roll. Switching those over, and suddenly there's a precipitous shift:
Porthos: 1184.798
Usukane: 1261.238
Why this shift? One reason is that by removing Hunter's Roll, the Porthos build falls below capped accuracy for the exact mob target value. It's only 5 points though, so I'll add an arbitrary 5 acc to keep things capped for the comparison. That only increases Porthos to 1199.585, however. The remainder is due to the Usukane build dropping to 2.13 rounds per weaponskill, compared to 2.72 rounds for the Porthos build. Without Samurai Roll, Porthos is at 2.74 rounds per weaponskill (ie: almost no change), while the Usukane build is at 2.78 rounds (higher than the Porthos build).
The minimum Sam Roll needed to make this shift is +25 Store TP. That puts normal melee hits at exactly 25 TP per hit, giving you a 4-hit build with the 25 Save TP. The Porthos build only manages 24.3 TP per hit with +35 Store TP from Sam Roll. The Porthos build would need an additional 6 Store TP to tip over into a 4-hit build, or 41 Store TP from Samurai Roll. That can be reached on a Lucky or 11 roll, giving 32+10 or 40+10, for 42 or 50 total +Store TP.
In the event that you get a lucky roll, things shift back to Porthos being slightly ahead:
Porthos: 1271.481
Usukane: 1265.948
So the main edge the Usukane build has is being nearly guaranteed to reach that tipping point, given that it will work with pretty much any safe Samurai Roll value, whereas the Porthos build needs Lucky or 11.
Note that the above numbers took a conservative value of 10% for Fighter's Roll. Higher roll values there increase total DPS, but the relative standings of the two sets remain the same.
Shifting the Usukane set back to RCBs does increase total DPS by a very small amount (1268.693), but removes a couple safe rolls from what will tip it over into a 4-hit build.
This optimization always depends on getting Lucky or 11 on Miser's Roll. The Porthos build needs Lucky or 11 on Samurai Roll. Poor values from Chaos Roll (dropping you under capped attack) favor Porthos (though not enough to make up for an insufficient Samurai Roll). Fighter's Roll generally favors both equally.
It's certainly easier to reach this DPS level with the Usukane build, though technically the Porthos build still has a higher max damage potential, unless accuracy comes into play; the Usukane build has a substantial 41 acc advantage.
