Think all those calculations are some way of the true representative odds. Putting in AJ+ and 22+ means you are assuming he has AA as much as he has 99, or AK as much as he has AQ which is waaaaaaaaaaaaaaay off imo.
28+ = old imo. Middle aged is more to do with appearence and personality then the actual age
No way do I think he has AA as much as 99 nor AK as much as AQ.
But I don't think he has 22/J10s as much as he has larger pairs nor larger broadways.
Nothing can be perfect when assesing the range through stove, it's not way off, it's a range assesment.
Personally I think the villain's range is rather largely weighted to 55-JJ, AJ/KQ/+
Versus this range the results I posted above are largely the same.
Aks is a clear fave, AQo is a flip, Aj is a dog.
