Hi David,
> A time signature is written with numbers, not durations.
Perhaps more completely (and, some might say, accurately): A time signature is
written with numbers, the second (“lower”) of which represents a musical
duration — specifically, the time signature n/d means “n events per measure,
each event having a duration equal to 1/d-th of a whole note”. e.g. 4/4 means
“4 events per measure, each event having a duration equal to 1/4th of a whole
note”, 2/6 means “2 events per measure, each event having a duration equal to
1/6th of a whole note”, etc.

I believe that Carl was using the future conditional version of “if…is” there.

Why not? 8/20 corresponds perfectly to “8 events per measure, each event having
a duration equal to 1/20th of a whole note”.
Cheers,
