Interpoker exchange rate

[theghost]

Sorry if this is one of those oft repeated questions... I searched without success.

Wondering about the exchange rate at interpoker - if I buy in with dollars at a table that is playing british pounds, then get dollars back when I leave the table, are they using an even rate?

If not, how bad is it? USD games seem to be a lot tighter (at least while I was there).
