That isn't a sufficient qualification - if you pad recordings (as I
do) then you can need two tuners for one channel to allow for the
overlap. Besides, I've just had a look and I make it 21 channels on
our Mux A (BBC), about 1/2 of which are radio, and one or two are
interactive (text) services, and some of the TV channels are part
time to share a bandwidth allocation.
So by a simplistic interpretation, you'd need a limit of 20 or more -
by which point, why have a limit at all ?

That text might also suggest that "5 is OK". I think a link to a wiki
page would be a good idea - then the wiki page can explain the issues
and how to choose a "good" number.
