In this case for the third upgrade I think the crit chance is accidentally switched on the first option and maybe miscalculated on the third.
My calculations show that using the 90 and 10 damage values with the crit chance from Survivors Edge, the Prisma Skana has an effective damage of 488 and the Skana Prime 380. However, if you switch the crit values(+2 for Prisma and +12 for Prime), the Prisma Skana has an effective damage of 432 and the Prime has 437, which are much closer. Leaving the current status effects the same, the Prime has 4% more raw status than the Prisma(30% vs 26%, for an effective 15% status advantage for the Prime). I don't think that would make up for the large difference of base damage but I haven't done the math on that.
Absolute Valor has the Prisma at 563 and the Prime at 392, switching them has Prisma at 443 and the Prime at 512. Neither of those are that close but this time the Prime has 10% more status than the Prisma(26% vs 16%) which is an effective 60% more status which makes a larger damage gap more justifiable.
Unless I have mad a large mistake in the math, I do think the crit values need to be switched on the first, and then maybe lowered 1-2% on the Prime to account for the 4% extra status.
