Part of this makes sense to me… effective teeth per second hitting the wood. We normally adjust this with number of teeth on the blade, and the motor speed stays constant. Reducing speed with the same blade would yield less teeth per second.

The part of the equation that doesn’t make sense to me is blade geometry. Blade gullet on a crosscutting blade or high tooth count combination blade often isn’t large enough to remove the waste. So even if you run the saw at a lower RPM, you may see burning. Interesting discussion. It certainly helps to have variable speed on routers, so I would be interested to see more research on this for tablesaws.
