User blog comment:TheDeadDragon/Fast LvL 3 Great Sword Charge/@comment-5043481-20121102152013

In MHFU you release triangle just before the end of the charge, this gets you a quicker charge. Or you can use the focus skill.

In MH3 you have to relase X (or whatever button is at the top) on the classic contoller just after the level two charge. You have to do this to get a level 3 charge at all. Or use focus skill.
