In this video presentation you can find what problem with FVP estimation using timing gates we are trying to solve by utilizing novel model definitions. We plan to do one simulation study and one multi-center, pre-registered study in a hope of confirming the benefits of using FVP estimation with different model definitions.
Yes and no. If you have single intentional max sprint data using GPS, then yes. It would be same as the radar (time and velocity). If you have bunch of data points over weeks of data (i.e., instant acceleration and velocity), then you will need to filter the maxes (crop the low acceleration data) and/or use the quantile regression. Think JB explained this in the blog post
