personal experience. I also do understand that sometimes having more teeth can cause issues at higher RPM, which is why I believe he is suggesting that a 36-1 should be used so that the cam sync comes in a gap. The issue with this higher tooth count I believe is that due to flex in the timing belt (along with stiffer valve springs/high lift cams), the cam sync could fall before the leading edge or after the falling edge of the tooth. This can throw the timing out by 10 degrees. Hence, by deleting one tooth, you've introduced a larger gap to reduce the chance of this happening. By running a 12 tooth crank, the gap between the teeth is much larger and you likely wouldn't have this issue.
