Here's an experiment with video. This is a clip of my Grand Prix Finals run with Lola from USDAA Regionals. It's at half speed, we weren't that slow. You can see how much time she wasted on the dog walk and I lost some time due to sloppy handling at the pinwheel after the teeter and my bobble after the weave poles but an otherwise nice run.
