I agree.  I've found the 3/4"x16" opening typical of the reversible
bottom board completely unnecessary at any time of the year.  I do
run with a standard 3/8" opening most of the time but do have it
reduced both spring and in the fall when yellow jackets typically are
a problem.    I have found that even with a very populous 5 frame nuc
a single 3/4" diameter is adequate so I'm sure even the standard 3/8"
opening is more than necessary.
