thanks for taking the time to nicely document these improvements!

Is an "or" missing before "above" here?

Negative. :-) Either somewhat is optimal, or it is not. You cannot be
more optimal than optimal. Let's just say "better", unless the code is
optimal now, in which case "optimal" is fine, too, of course.
Proposed patch below, but not committed yet. What do you think?
