How accurate is the Estimated CdA?

The physics behind our analysis algorithm is sound and we have shown against velodrome and wind tunnel data that the deltas between an athlete’s position can be picked up nicely. As we get more data we will continue to refine our methodology especially around our clustering algorithm which does tend to error a bit on higher side for drag settings. This is somewhat purposely so athletes and coaches don’t have overly optimistic expectations that can not be met in reality as we have seen with some wind tunnel and velodrome data in the past.
