I hand show and make an average 33% profit weekly. But horses don't stay "in the money". The horses that placed well this week will go up a level and take a while to get back up to being competitive. The horses I'll show next week were competitive 5-6 weeks ago and the ones the week after that 6-7 weeks ago.
So you have a constant cycle of horses placing well and being competitive and then "resting" while waiting to train up and become competitive again. The BM just calculates who is most likely competitive TODAY, not who's competitive every day.
If you still want to sell off the horses who will be making you money next week or the week after that you can see under Reports your Show Summary, which will tell you which horses showed this week.
