I found the 16" winner comparison even more interesting. The main point was to show that it's the tight turns caused by adherence to the handler's front cross line that can really make or break a time. I try to be mindful of the front cross line when I'm running Pimg and will often find a spot on the building wall as my "reference" spot on where to cross. This helps to keep Pimg's line tight through a series of jumps where I need to cross. It never ceases to amaze me how wide some people let their dogs turn. It can literally add up to seconds of wasted time. This video points that out (though on the decisecond level).
