Mixed team: three different models share one bankroll.

661 / 661

Action timeline

Model's stated reason

No count information, first round, minimum bet to conserve bankroll.

Model's stated reason

The shoe is fresh with no count information, so the minimum bet limits variance while matching the teammate's suggestion.

Model's stated reason

The Hi-Lo running count is +3 with about 5.8 decks left, so the true count is roughly +0.5. That gives no meaningful player edge, so the minimum bet keeps expected losses low.

Stated reasons appear after the comparison block is revealed. They are model-submitted text, not verified reasoning.
