Advice needed from my fellow BLM's regarding AS2

[RajaVamberaux]

3xF2 -> Flare -> Transpose -> T1 -> F3
3x3s + 4s + (3s) + 2.5s + 3.5s = 22s
3x~540 + ~1276 + 210 + ~200 = 3306 potency
3306/22s = 150.27 pps

2xF2 -> Flare -> Transpose -> F3
2x3s + 4s + (3s) + 3.5s = 16.5s
2x~540 + ~1276 + ~200 = 2556 potency
2556/16.5s = 154.09 pps

I see. Thanks this is really helpful. I guess now my question is the difference in these two options isn't concrete because you may need to wait a few seconds for a tick after the transpose - wouldn't it be helpful to get used to casting T1 for long-living mobs in order to proc more thunderclouds?

EDIT: nvm I see you've accounted for the transpose wait time (3s in your calculations).

EDIT2: Since I have your helpful attention, here's another question: how many mobs would it take for 1 thundercloud proc on a non-DoT'd mob to be more potency than a Fire II? Or vice versa if a thundercloud proc is more potency by default
