Looks good. Not really work it longer (at high speed), but stage it down, reducing the speed as you get to your final speed. I usually:
1- spread @ 1 (a few passes)
2- bring it up to 3-3.5 (until broken down)
3- reduce to 3 (a few passes)
4- reduce to 2.5 (a few passes)
5- reduce to ~2 (a few passes)

I usually keep my finger on the dial and adjust speeds w/o lifting the buffer (trigger locked). I kinda go by feel and sound of the buffer too.
