Hey guys. I’ve been using the double double as a way to train and test my jumpers for some time. I know the double double is supposed to project TJ performance, but I’ve found my athletes double doubles to be superior to their TJ, sometimes significantly. I was wondering if anybody else has found this to be the case?
Normally there is a discrepancy of about a foot, so I just subtract a foot and its pretty accurate, but I have a girl who’s 07/08 PR was 33’3” who double doubled 36’10” yesterday in flats. She is faster, stronger, and healthier than she was last year, but I would be shocked if she PRed by 2 1/2 to 3 1/2 feet. I’m confident in my coaching, but I’m also realistic.
Is this a common occurance, and if so does anyone know what the problem may be?
