I had a count around 38 (KO) once, but I distrusted my count. I figured I must have slipped by ten or something as I kept seeing 4s, 5s, and 6s coming out like flies. Also, a KO 38 is a TC of 21 (with 2 decks remaining), if my calculation is correct, so it's not as high as it seems. I lost my shirt going up in the count, but got most of it back on the downside. One good thing--even if I did lose the count by ten, which was mostly my paranoia of the moment I think (second guessing myself), the count would still have been high enough (+16) to warrant max bet.
