Leap skill - when to Leap?

Hi all,

When does the extra movement from Leap get applied, specifically during a Charge? Our group had a disagreement over whether it's strictly as mentioned in the text ("...Charge and Leap"), since it wouldn't make sense if you didn't already have enough MV to Charge before adding the extra from Leap - you would've already failed the Charge. So we allowed "Leap then Charge", which allows the model to Leap out from behind total cover, and then Charge a previously unseen opponent.

BUT! From the few existing threads on here, it seems people play it as you add the +d6" Leap movement into your movement allowance for the Charge (or Walk, Run - whatever), conceptually meaning that at some point during the model's Charge, it does a Leap (so as to avoid Intercepting models, or to get a Diving Charge off, or cross a gap, w.h.y.). Doing it this way would NOT allow a model to Leap out of cover and then Charge, right? Since LOS isn't available at the beginning.

Any consensus about how to play it?
Thanks!

Leap. The warrior may leap D6" in the movement phase in addition to his normal movement. He may move and leap, run and leap, or charge and leap, but he can only leap once per turn.

We play RAW.

If your warrior wants to charge an enemy model within 4" that he can’t see (eg, because it is behind a corner) but has not been declared as hidden, he must pass an Initiative test to detect it. If he fails the roll, your model may not charge this turn, but may move his normal distance, shoot and cast spells.

Leap's no help in this situation as charges are declared before normal moves and your enemy's within 4" anyway. Even if you allow the leap to come first, I'd say that would count as a normal move.
