If we limit the number of points to a certain place, say 10th, then the 12th participant in 2 and the 38th in 3 will have an equal number of points, and the winners will also have an equal number of points, unlike your proposal.
My proposal is post №12 (/topic/at/58925/)
I will provide the point calculation table a bit later at AlexeyPank`s request.
