New PDR Indicator

Im an idiot for believing my friend, disproved his theory, funny how hes the korean guy that played kms for 5 years.

just because he's korean doesn't mean he is good at math hahaha, that makes things simpler then

wait so, assuming it is additive,

A=(1- window number/100)*(1-snipe PDR)(1-snipe hyper PDR)

PDR=100*(1-A)

A = (1 - .84) * (1 - .31) * (1 - .10) = .09936
PDR = 1 - .09936 = 90.064% pdr

so if i am fighting Chaos Vellum, does that mean i take away 90.0% of the 300% = 270%


so my damage is reduced by 30%?

edited with the new info for the correct way/numbers then
