If he sticks to a strict strategy, then the only thing stopping him from playing more and more is how quickly he can move his mouse and click. Since he's had the training for this I think it's quite realistic. The only dodgy thing is that he chats.

I think I could mange 20 myself, and I've only had some 12 tabling experience (I jumped from 6 to 12 with no problems, and now do 10). If I could manage 20 without much experience, I have no doubt someone could manage 30 with alot of experience under their belt.
