Awesome! The calculator on A&A.org has limitations as you point out. The Triple-A one doesn’t give info like the one and two standard deviation results.
My 87 year old Dad, a WW2 veteran still plays using the OOB rules(corrected). He would very much enjoy an OOB rules version of Triple A for when we all can’t get together for a f-t-f game. And to practice, too I presume.
