Power users > light users = significant loss
Power users < light users = significant gain

It's a gamble which was my initial point. Your always going to attract heavy users with an offer like this because it's laughably good value for them but you'll lose money servicing them. The flip side is if you can attract large numbers of regular users it doesn't matter you'll make good coin regardless.

It's going to be a volume game.
