Fine-Tuning PLD rotation - tips?

[Reynhart]

Using Fracture is basically a .3% dps increase at the cost of a 6% increase in TP consumption.

If you clip GB, then you may have too much skill speed.

I've made a calculation on a 90 GCD window and using Fracture is a DPS gain only if you clip GB on at least 9 full rotations. In real situations where you probably move a little and might lose some tenth of a second, it's mostly innefective.
