And whose fid? Most splicing instructions say "measure x fid lengths" but
seldom state it in inches or rope diameters. There are several makes and
different lengths of each but there are less fid sizes than there are rope
sizes so how would you define a "fid length"?

Interesting question. I can only guess but I think a fid length is
the fid you're using I suspect the variation doesn't matter except
how hard it is to make the splice!
