The Real Problem with Parsers

[Viridiana]

In practice, we can calculate the Full Thrust combo's potency, including our base buffs as Dragoon (Heavy Thrust's +15% damage and Disembowel's 10% Pierce debuff resist drop):

150+200+360+290 = 1000 potency
1000 / 4 = 250 potency per gcd
250 x 1.15 = 287.5 potency per gcd (with Heavy Thrust)
287.5 / 0.9 = 319.44 potency per gcd (with HT+Dis)

And then you get in game and realize that your calculations are off, because 1) potency scales weird and Full Thrust isn't 12x as much damage as Phlebotomize ticks, even without buffs, and 2) that Disembowel should probably be X*1.1, not X/.9. At least, that's what the community's been using.
