That code is checked on a per-source basis, so unless you have two
grabbers putting data into the same source, then it should work ok
because on one source you'd have 13/13 and on the other you'd have 0/2.

Putting 0.90 there was just an arbitrary limit.  I think I'm the one
that added that logic.  The code tries to make sure that we allow for
cases where some channels don't have data, but force a refresh if too
many don't.  It shouldn't be affecting you if you have 2 sources as
