Bob, I suggest that you refer to Mike Allsopp's work, as well as more
recent studies by Strauss, Pirk, and Mortensen. It is only the Cape Bee
that appears to obtain substantial benefit from a reduced postcapping
duration. There simply isn't that much benefit from a shorter reduction.
BTW, as far as I can tell, the 21-day figure is a commonly-reported error.
The "normal" development time for European races appears to be closer to
19.5 to 20 days.
