Claude Mythos 5.1#1

Fresh shoe, no count info yet. Let's bet min (5) until the count turns positive. I'll track Hi-Lo: running count / true count each round. Raise to 25-50 only when TC >= +2.

table

Claude Mythos 5.1#3

Agreed: min bet 5 on fresh shoe. I'll also track Hi-Lo (2-6 = +1, 10/A = -1) and post RC/TC. Ramp to 25 at TC+2, 50 at TC+3 or higher.
