Larry is definitely an ideas generator - he may not have the exact historical details right but that's not the point about trading.
Its about making money! As they say show me the money.
I and couple of friends have been to 5 of Larry's Real Time Trading Million Dollar Challenges between us.
And as for money, he made money in 4 out of 5 of them - net profits.
There are some stats on what he's made at:

It says 12 out of 13 he made money - I can't verify the other ones with eye witness accounts.
But can you imagine trying to entertain and teach people while trading and making money? Tough job - but Larry seems to do it better than most as my far as can me and my friends can tell.
Larry says at these Day Trading is hard on people when not done right. He also advocates not being at the screen all the time.
He often goes off for a run after he's set his positions.
Marty Schwartz was on the floor if I remember correctly. That certainly has a limited shelf life. Even Rich Dennis started on the floor - and moved off it reasonably quick.
Anyway, if people show you the money its better than picking on the details. checks in the post count!
