Credit rules

  • Credit "Dogleg Data" and link doglegdata.com (the badge on the chart already does the naming if you keep it visible).
  • Keep the source line and any "modeled" labels on the image. They mark which numbers are published data and which are extrapolated, and cropping them changes the claim.
  • Want a number checked, a custom size, or a scramble read run through the model? Email sunny@doglegdata.com. Same-week turnaround.

Boilerplate

Dogleg Data tests golf's conventional wisdom against real data at every handicap, with every source cited and every modeled number labeled. Built by Sunny, a data analytics professional, it publishes the charts and the models behind them under one tagline: play the percentages.
