If you actually understand this, you realize that Fracture is nowhere *near* being cost efficient. If TP were a static value with no appreciable regeneration then Fracture would be efficient. However, because TP is *not* and has very substantial regeneration, Fracture is anything but.
False. I'm not ignoring TP regeneration. I'm calculating on a per TP value. That includes values from regeneration. TP regen has absolutely no bearing on efficiency. Period. Ifyou believe otherwise, you are simply in error. You are calculating a time to empty "reserve" TP. This is meaningless for the purpose of determining whether or not to use Fracture. Efficiency and damage per CD are the only things that matter.

Yes, there is. We're talking about comparative increase in damage per GCD by using Fracture rather than not using Fracture. Fracture is an extra 80 TP for the GCD in which it's used. If you're looking at the percent increase over damage per GCD, you *have* to look at the damage provided by auto-attack. If you're not, you're simply attempting to inflate Fracture's contributions to make it look good, just like you're trying to make Fracture look good by ignoring TP regeneration.
False. Auto attack is a constant and can be ignored. Furthermore, your inclusion of auto attack actually cause you to commit errors by including by assuming that running out of TP halts auto attack.

I'm not attempting to inflate fracture's contribution. It is a small increase in DPS and a small increase in efficiency in many circumstances. Incremental gains are a critical aspect of min / maxing which is what theorycrafting is all about. Yes, Fracture is very frequently worth using. Your math is incorrect if it says otherwise.
