Anyone playing 10 tables with the beta software?

Wouldn't most 2+2ers only playing 4 tables have an advantage over those playing 10 tables, since 10 is a lot to focus on? I mean, I realized a guy was 10-tabling the other day (and he won some money doing it) because I was playing at two of his tables, so I opened all of them, got a great PT/PA read on him and spanked him good.
