if you are only interested in a running total, then I can't see the problem with multiple sites on the same spreadsheet - however, it wont show which sites are profitable for you and does skew the figs (as your bankroll will be disproportionate to the buy-ins)

You might actually be break even at one site and think you are great, and not so good at other but actually doing quite well.

I would chose the option of separate spreadsheets for each site and see where your long term value is

Just my thoughts
