speed also has alot to do with blade type. If you're using a smaller blade in thin material, The faster you cut, the more tear outs & chipping you'll get. Easy does it until you find a speed that does a good cutting job, & little tear out.
on the other hand, if you're cutting in thicker material, say 1/2", try a #3 skip tooth, or an UR #3, & cut at different speeds to see where the sweet spot is, & leave it there. Every blade type & size will react differently at different speeds. You just have to play with the variables until you reach your satisfaction point. jmo.
Speed works against blade control, as well. If you're cutting to fast, you'll have less control. To slow & you'll have better control, but at the same time, you may want to rush the feed rate, & break blades, & have crooked lines. Remember, the smaller the blade, the more tension you'll want. The bigger the blade, the less tension you'll want. It all works together, & takes practice, practice, practice.
