As for doing sorting for a long time, not really. We have sorted before, but we actually normally do team penning (We've done a short season every winter and spring since I was little...) But we lost our third person so we have been sorting this year instead. Normally it's me on Selena and my partner on her horse.
Doesn't matter anyway now, the barrel race ran WAY late and we missed the sorting. Oh well, next time.
