At least when mini-raising and shoving, the width of the range, that is, the boundaries, is known. In this example, the spectrum will be no narrower than 0.9% and no wider than 4.2%. Those, we are unlikely to make a very big mistake if we always call (in push/fold stacks) on the average between these two ranges.
But also yesterday i invented another rule, i just didn’t immediately write it here. The rule is: multiply the numbers in the overcall column (OC) by (Pi - 1)=2.14
Joke, multiply by 2.
Then for this example, we get a 1.8% call range, or about JJ+, that is, a tighter range. It would probably be better that way.
Maybe someone who has a non-browser program with wider functionality, and who has extensive experience playing in a variety of spots, will advise something...
