The purpose of data, and the technology you’re using to collect the data, is to help you answer questions. Independent validation of the technology therefore ensures that the data you are collecting is answering the questions with the correct information. Using Catapult correctly will help you get those extra percentage points of performance out of your athletes, but if you’re using technology that is not independently validated using correct scientific principles, you could be causing harm to your athletes by basing your decisions on erroneous data. When it comes to data, if it’s garbage going in, it will be garbage coming out.
