Leti Cro, I've read again your post, and I found some things I believe you would like to change if you're still into the topic of machinists :
1) You changed a 255 potency in 355 for your calculation (see google sheet in D-8).
2) You put 6 GCD in your Wildfire rotation instead of 5. I'm wondering how, and you don't speak about your Skill speed and/or technique to explain it and it's not for nothing people speak about the combo "Cooldown-3-2-3-Cooldown" (so only 5 GCD possible, imo).
3) In K-16 "availible"
4) In D-16 you said Slug Shot + Gauss Barrel + Barrel Stabilizer give a total of 400 potency instead of 200.
5) In H9, numbers with so many decimals like 871,5196875 are irrelevant, it only can make people who dislike numbers but are still interested in the topic to run away. We talk about potency where a single point doesn't change that much, so 871.52 was way enough to still give decimals.
6) You didn't put the Hot Shot multiplier in your calculation, which mislead to see the total potency given by Overheat. I know you said you did it on purpose and thought we would just put it ourselves. It's ok to do so, but it's not really helping for average people to get an accurate number as I guess average people won't bother adding the +8% by themselves to see the difference.
7) In D-3, you changed a 190 potency in 390 potency. So I guess you forgot to write you did a Gauss Round right before Split shot, so you should add a note about why you count it this way in the "Note" part you made.
