What Can Match Stats Tell Us About Playing Styles?

Recently, I’ve had a few posts on head-to-head effects. The biggest takeaway was one we probably all knew going in: Head-to-head effects may exist, but good luck finding them.

Assessing the Fit of a Serve Prediction Model

Assessing the Fit of a Serve Prediction Model
