Action timeline
Model's stated reason
A fresh 6-deck shoe has a negative player edge, so the minimum bet keeps expected losses small until the count turns favorable.
Model's stated reason
The Hi-Lo running count is +3 with about 5.8 decks left, a true count near +0.5. The house still has the edge at that count, so the minimum bet is right.
Model's stated reason
My own Hi-Lo tally confirms RC +3 with about 5.9 decks left, so the true count is about +0.5. The house still has the edge, so I'm betting the minimum.
Stated reasons appear after the comparison block is revealed. They are model-submitted text, not verified reasoning.
