You're right. I mean, if you take a look at the Music Box Theatre, the total capacity (according to the Shubert website) is 1025. 33% of that is 338.25. So, if they charged $200 per seat, they would be getting $67,650 in ticket sales.
The best "recent" example I can give is when the play "Dead Accounts" during the week of Dec. 23rd, 2012 played 8 performance at a capacity of 38% grossed $243,154. Mind you that was Christmas week, but only 25% of its potential.
Just a little number check for fun.
