SDS and I were talking about this yesterday, but I would appreciate some confirmation...
Say Drifloon is holding Berry Juice and gets knocked down to 50%. It consumes the Juice and goes back to 100%, losing it's Burden and doubling it's speed. It gets knocked back down to 50% (Phanpy used Ice Shard) and Drifloon uses Recycle. Drifloon consumes the Juice again, going back up to full health. Does Drifloon's speed double again?
And today will be better than yesterday.
