The purpose of Fracture isn't so much the miniscule increase in overall encounter DPS as it is to delay Demolish so that you don't clip the previous application before you get every tic of damage in. If you're at 5s left on your last Demo and you're back to Coeurl, your options are to a) Demo and lose a tic, b) Snap Punch and lose Demo on target for at least a single tic, c) delay by reapplying Touch of Death. Option C is a winner... unless you'd be clipping ToD short too.
Fracture gets you around that. You delay Demo by approx. 2s with Fracture and that lets the last tick of the previous Demo occur at exactly 3s left on the DoT. Then you hit Demo to reapply.
...of course, you can do the EXACT SAME THING with Meditation in place of Fracture, which leads you reach Purification faster to restore some TP and solve all TP issues.
"But muh Forbidden Chakra!"
FC is appropriate in some cases, not all. Read: openers and when you're sitting pretty TP-wise.
tl;dr: Fracture is optimal but not worth the drain outside of hardcore Savage raiding, and MNK has no TP issues courtesy of alternating between Invig and Purif. Oh, and any MNK who keeps Fracture up 100% of the time in a 7+ min fight is bad.
