Blackjack Strategy Trainer v2 Feedback

The Blackjack Strategy Trainer version 2 is fun to play but there's one major problem that I would like to see addressed. The game slows down drastically after like 3 games have been completed on a 2 deck BJ game on my computer and while using my phone. That's a problem. Everything else seems fine but the "slow down" has to be fixed. After playing a 1000+ hands over the last few days I wanted to make sure I left feedback so the issue can be resolved. The speed that the game starts out at is the speed that the game should be played/maintained at depending on how fast the BJ player is making decisions with a click of a mouse.
