I'm looking to know how much I will need to charge my horn from being empty (waves and/or %) to get 80 Agility at Ape Atoll (approx 960k exp from where I am now).

Thanks for helping. (:

It's hard to say for sure because the xp it lasts depends on your agility level but 1 completely filled should get you your level.

You could also just fill it up for a whole round of BA, then go use all that xp, then come back for a break. Its only slightly longer this way, and you wont get burnt out as fast

I'd say about a full horn, but don't try to do it all at once. I could honestly never get my horn more than half-full before i had to use it. :mellow:

This is exactly what I do.
