Understanding Ashe's Passive

so after playing a round with i began to look into her passive a bit more. her passive, Frost Shot, makes it so her crits do no extra damage. that sucks yes but if we read it in depth it says that enemies hit become Frosted for 2 s and all attacks done to Frosted enemies become mini crits doing 1.1X damage. however this can be increased with crit items. so say add it becomes 1.4X. so how does this interact with ? well lets look at a math problem. we'll use 100 as the base dmg.

Normal crit: (dmg X 2) / 10 = 20 true dmg and 180 crit dmg. Ashe crit: dmg / 10 = 10 true dmg and 90 crit Ashe crit vs Frosted enemy: (dmg X 1.1) / 10 = 11 true dmg and 109 crit dmg.

so while her crits do no extra dmg on their own they still count as crit dmg so passive does trigger. how does it work with ? i do not know yet. the first shot that triggers SR will Frost the enemy, meaning they were not frosted before, and only do non-Frosted crit dmg. and the Frost only lingers for 2 sec so you can't idle long enough to let SR recharge and shoot the Frosted target.
