The estimate of our tricks for the general case.
E(tricks) = trumps + (HCP-20)/3 + e
But I suspect it is really
E(tricks) = 8(=4+4) + (HCP-20)/3 + e
where the expected value of e is zero.
E(tricks) = 8(=5+3) + (HCP-20)/3 + e
where the expected value of e > zero.
Not clear how much greater than zero.
Definitely less than 1/3 of a trick.
Only it is difficult to find an unbiased sample
to test this assumption.
Your partners are probably over adjusting.
They should just bid game with a 5-3 major
fit and at least 25 points. Let the opponents
play game with 24 or less.
