When multirec was being developed 5 was decided on as the point where performance was still good on contemporary hardware. You can change the limit and re-compile if you need to, a friend's system handles 8 SD channels with no problem on a 2.6Ghz C2D, multirec set to 10.
I mostly record HD and currently there are 4 channels to a mux, it's not that often an overlap causes me to "waste" a tuner.
with the way broadcasters are cramming more and more channels in to one mux maybe this default limit needs re-assessing.

Then there are overlaps too!
