Corrections: On the 1st graphic it shows an added weight hanging from the con rod as being 69 grams. That should be 25 grams which is what you get when you use a balance factor of .22 which is way off from the recommended .5 to .6 factor. I never actually tried to static balance it and I no longer own that engines crank. I left it back in Ecuador. The needed static weight was calculated. How that is done is by multiplying the weight by its center distance from the pivot point (center of crank) and comparing that to the opposing weight multiplied by its distance. I just recalculated and it comes out to being 25 grams. I don't know why I put 69 grams. It must of been late at night. Also the spreadsheet has since been updated to include the combustion pressure.

The moment i realised your idea my brain went crazyyy
I hope that was the good kind of crazy
how can i get or avail the program?
