Right now they are private constants in ceval.c.

I will (maybe) expose a private API via the testcapi module to re-define them (set them to 1 or 0), only to write better unittests. I have no plans to make those constants public or have a public API to tackle them. IMHO, this is something that almost nobody will ever use.

Alright. I agree with you on that.

What I actually meant was: how can we find the optimal values? I understand that 1000 and 20 are some hand-figured/subjective values for now.

Is there standardized/objective way to find out the best values? What does best even mean here?

Best, Sven
