Anyone who is genuine about promoting their posts will not use bots after 2 days. Posts move off the hot list in less than a day and many posts rarely make 3 days on the trending list. @boomerang and @booster have the right idea with 2.5 days. I recommend that Grumpy Compliance should be adjusted accordingly.

There is another problem of people posting 2 minutes before a bot bidding session expires and then bidding on a bot to bring the max bid below zero. The last minute bidder gains (no curation payout) while all those that voted earlier lose out. This is abuse of the bots and something Grumpy Compliance should also address.

I strongly believe Grumpy Compliance is in need of updating. I hope you take these points into consideration.
