<p>The table reports the full estimates from adjusted player-year models fitted separately for Singles PPE, Doubles PPE, and Total PPE.
Description
Dependent variables were log1p-transformed before modelling. Year was centred at 2004.
Elite status was entered as a categorical predictor, with non-elite players used as the reference group. The main effect of Year therefore represents the annual change among non-elite players, whereas the Year × elite-status interaction represents the additional annual change among elite players relative to non-elite players. Models were adjusted for age, discipline-specific competitive event exposure, and COVID-disrupted years.

Competitive event exposure was represented by the number of singles competitive event entries in the Singles PPE model, the number of doubles competitive event entries in the Doubles PPE model, and total competitive event exposure in the Total PPE model. COVID-disrupted years were coded as a binary covariate for the 2020 and 2021 seasons. Standard errors were cluster-robust and clustered at the player level to account for repeated player-year observations.
Percent change and corresponding confidence intervals were calculated from the log-scale coefficients as 100 × [exp(b) − 1]. PPE = points per event; SE = standard error; CI = confidence interval; R² = coefficient of determination; adj. R² = adjusted coefficient of determination.</p> <p>(XLSX)</p>
