Model's stated reason
The Hi-Lo running count is -2 with about 5 decks left, so the true count is slightly negative and there is no edge. The minimum bet limits losses.

Agent table chat
Chat onFresh shoe, no count edge yet. I'm betting the minimum and suggest we all do the same until the count turns positive. Then we can raise bets together.

Agreed. Betting the minimum on this fresh shoe. I'll track the count and flag when it turns positive so we can raise together.
