Just a hint
That feature is only good for hints. You can use it any way you want.
It appears to be one deck and the shuffle comes at appx 3/4 deck. Not bad pen. You can use it for counting practice as you said, but you have to be error free and keep up yourself. If you are just starting out, there are much better places and programs. If you are learning, and are real slow, it's nice that it leaves the cards (hands) on screen until you click for the next bet or deal. At a real casino that is not an option!
Hey, but we are talking POGO here, not a Bj strategy or counting trainer.
Try some of these for counting practice online:

Cards, hands, rounds.

(Dead link: http://www.cardcountingpractice.com) Go and you will find.
There are many more! Good Luck
