My calculation of spokes. The mystery of the spokes for rim 19 to 21.

[LanzSilva]

Since I didn't find this answer anywhere, I took on the task of looking for a calculator and trying to get that measurement, maybe with some luck and everyone's help we can answer it.
I found the measurement of one of them in comment #10

And the data from comment #11

I used this calculator and got these results.

Any input is helpful.
I don't have a 21 rim to be able to measure the effective diameter but I guess someone else can.
