actually looks like it would have to be
71' 1.5" if the mound is still going to be 60' 6" away.
couldn't you place the bases anywhere you wanted, without having to move the mound?
i'd like to incentivize speed, but it should still be a little bit hard to get an infield hit. so maybe 84-86 to first, then second should be fairly short distance because it's pretty easy for the pitcher to hold runners on first. third should be farther from second, since third would be the easiest base to steal. the third-fourth distance should be maybe just a smidge shorter than 1st-2nd. and obviously the distance from t4th to home should be the shortest to facilitate the most exciting play in the sport.
