Find the leak before estimating its cost.
Classify pay-table, hierarchy, penalty-card and speed errors without inventing a universal loss rate.
Wrong pay-table chart
The same cabinet name can contain several schedules. A chart trained on 9/6 Jacks or Better does not automatically transfer to 8/5 or bonus variants.
Hierarchy errors
Players often overvalue four-card straights, break profitable made hands, or keep visually appealing low cards. Exact rankings depend on the schedule.
Penalty-card errors
Discarded cards can remove flush or straight outs. Expert strategy distinguishes hands that a simplified chart groups together.
Speed errors
Increasing hands per hour multiplies both correct-play expected loss and mistake cost. Multi-hand play accelerates action further.
Measurement
Mistake cost equals EV of the best hold minus EV of the chosen hold, weighted by how often the state occurs.
