How do people use best-value?

[swapneils]

See the title.

There are some improvements I'd like to make to the best-value semantics, most importantly to only run objective-form after the first run of form1 has completed.

I'm fairly certain the current behavior is a bug, given it doesn't at all reflect the general goal of "optimize the selected nondeterministic path to be 'best' by some measure".

If people are not depending on the current behavior, I'll just make the change in best-value itself. Otherwise, I'll have to make a new form (optimize-value?) to provide the improved behavior.
