Xavi,

So, you are saying that in order to measure jump height accurately I will need a camera system as well?

If not, then I was wondering why there is such a difference across contact mats (Chronojump and Just Jump). When using both combined with a vertical jump measuring device such as a vertec, there is a considerable difference is estimated jump height (different formulas?). The measure for the Chronojump are consistent among themselves. Sorry to keep going but I am just curious by nature.
