Yeah, I noticed that too... sometimes it stays the same, sometimes it add up 10 (or 5) and sometimes goes back to full between two battles.

The only explanation I could think about it that it's some weird effect due to the way RPG maker works like how if you use some power up ability three times it will show only two "up" arrows but it will apply the power three times...
