...if by "a while" you mean "a year or two", because I can't imagine
that restriction surviving much longer than that.  You can already get
off-the-shelf hardware with 64 threads per die.  If screen real-estate
is a concern, we can switch the scale from 100 to 1, so 1.0 is full tilt
on one thread, etc., and use "%.5g", which should work for up to 99999
threads (9999900%)
