Aha, thanks... I feel this has potential for speeding up things.

That was on a new incremental attempt with -i:all (replaced with a custom .chr).
As
for the rules, I think the most I've waited for the rule processing was
something like two minutes. As far as I'm concerned, the indicator
resetting every once in a while is a minor bug. Especially if the rules
are [a-z] type where you can plainly see the progress by the first
letter. For other rules it may not be so clear but I generally calculate
the time needed with a spreadsheet even before I start the attempt (old
habits...) so I have a fairly accurate idea of the time left.
