Regarding critical damage with the revamp

What sort of testing would need to be done. My aran has crit ring + a machlear, and I could get someone to SE me. I just don't like using it except for display purposes as I don't wanna bring down the durability % and end up paying to fix it T.T

Scenario 1: 70% Base Crit + 15% SE + 10% Ring + 5% Machlear = 100% Crit rate
Scenario 2: 60% Base Crit + 15% SE + 10% Ring + 5% Machlear = 90% Crit rate

About 10minutes of keyboard smashing should yield a fair confirmation.
