Who this is for
- Analysts comfortable in R or Python who want to build rating and ranking systems that hold up in practice.
Not for you if
- You want the math theory without building anything
- You've never written code in R or Python
- You need a finished library, not to understand how it works
- You want a single-sport tutorial rather than transferable methods

Reimbursement email template
Subject: Approval request — AthlyticZ workshop: Rating and Ranking Systems in Practice Hi [Manager], I'd like to enroll in "Rating and Ranking Systems in Practice," a live 4-session workshop from AthlyticZ (Oct 7, Oct 14, Oct 21, Oct 28) led by Maddy Brown. Over four sessions you'll build and evaluate the rating systems behind real sports rankings — Elo, Glicko, and beyond — on real game data. It is directly relevant to my work, and I'll finish with a concrete deliverable I can bring back to the team. It includes live instruction, lifetime replays, and a provisioned enterprise Posit workspace. Could this come out of our learning and development budget? I'm happy to forward the receipt and a certificate of completion. Thanks, [Your name]
