Analisys of potency of thunder

Thunder 3 adds 1 60 pot initial cast, 2 70 more pot for 2 more shots, 3 probability to proc at least once thunder cloud goes from near 30% to near 37%

so we have:
100% 60 more potency
7% of doing 340 potency we didn't get with tunder
30% to get 100 more potency if trait proc early on
70% of doing 70 more potency if trait not proc or proc on the lasts tiks
total
60 + 23.8 + 30 + 49 = 162.8 more potency for 1 second cast time and mana

the answer to ask now is, how many potency/sec the rotation with thunder 1 does? With mana pool cast thunder 3 means 1 less cast of fire 1? (the difference is 213 MP way lower than fire 1 cost under astral 3. At worst, you need to add 213 MP to your mana pool in some way)
Is 5% proc accurate, some mob have way to lower it? (i noticed with fire starter that on some bosses it seems to proc way lesser than expected, like once in 2 rotation <.< I don't know if i'm just unlucky but it happen only on bosses....)
If the rotation does more than 163 potency/sec then thunder 3 is not worth it

I don't know exactly how much potency/sec is our rotation, so i'll need some more input here from someone that have done more math than me on this
