Rough Cestus damage percentiles:

I was bored. And I was curious. So I guesstimated some percentiles for some of Karok's Cestus attacks.
Methodology:
-I needed something I could easily ATT cap on and could easily OHKO, so I chose to hit White Spiders in Perilous Ruins (100 HP).
-Took screenshots and recorded damage numbers.
-To account for crit, I took the absolute highest damage number (assuming it was a fairly high balance roll) and divided it by my Karok's +crit damage boost (which is .62585). Any numbers that were higher than that were deleted since I didn't feel like doing extra maths for crit (you don't see the crit numbers in the spreadsheet).
-Took the average damage, added 100 (to account for the spider HP) and then reversed the damage formula found in here.
-Then I realized there's no point in taking the average damage, and only wanted to get the highest damage (because that would better reflect a 100 balance roll).
-Took some assumptions with how the attacks worked: since I used Weave Attack to make getting LR/LLR data easier, I assumed the skill modifier for those two attacks were Smash + Weave. Also, Blast is not effected by anything but Blast, and Big Bang Attack is not effected by anything other than Big Bang Attack and the level of charge on the blaster
So yeah, poke holes in my methodology if you can, it'd actually be helpful. And I also need larger sample sizes to get more accurate numbers (I was running Red Ruins on hard and just fell down that first pit-area and killed all the spiders there for one reading) so these are mostly guesstimates.
EDIT: So apparently it seems that Weave Attack isn't the LR or LLR smash, it just looks like them. Had to revise the chart to account for that because it has its own percentile.
