Sears quotes the max hp developed by their motors *at stall*. While this is 
a legitimate rating it hardly reflects the true capability of most tools. It 
works great with a table saw because as you bog the motor down in cutting 
heavy material the hp increases to stall but a compressor or sander or other 
tool that does not go to stall is considerably overrated by this method.

Just my $.02
