Actually, the weight limit for prospect steers is 875 at the BBB. Everything over that shows as progress. The progress show is much smaller than the prospect show at BBB. Progress steers showed on Monday, prospects on Tuesday.
For some reason, almost all of our shows down here developed the multiple ring system where you basically have independent shows under different judges. I still don't particularly care for it, but it worked out well for us at the BBB (4th Overall in Ring A, Grand Champion in Ring B). Multiple rings makes shows last forever. But it does do a good job of getting your calves used to showing for long periods of time which helps for the majors.
For practical purposes, progress calves this time of year are usually headed to the State Fair of TX, KC, Louisville, or Denver with some of the smaller, slower growing ones working for Fort Worth.
