I've been working on the road to becoming an AP. I started with learning PS and was able to complete 1,000 hands without error. I then learned to keep the running count and calculate the true count, being able to keep count through many shoes on an app and keep perfect count with an at-home 6D shoe I made.

Having attention issues I have started playing PS level bet at a few stores to practice keeping count in the real world before adding in the final step of deviations. It's been hard - very hard. (I don't have anyone else I can practice with so I can't effectively back-count in a store).

In doing this I have come to observe one thing which is nearly as true as a rule: I win far more hands when the count is very low and I lose far more hands when the count is very high. It's gotten to the point where I walk when the count gets outrageously high because I lose nearly every hand. Low count: I rack in the wins.

This seems counter-intuitive. Highly.

Is this the norm? Are the plus-counts only beneficial when applying deviations?
