Hi Ian,

Just discovered your substack through Hugh Clarke's, and as a fan of technical and analytics deep dive, I gotta say I love it. Read it, keep it up.

One question about some of your formulas, especially adjusted total points won. How reliable do you think Tennis Abstract's TPW stat is? I'm sure you use it as the basis for your complex formula that runs through an algorithm, but I, as a beginner, how much trust should I put in those?

For example, you mention Hurkacz having a 50.8 aTPW for 2023, whereas TA gives it at 51.3. What do you think of it? Is it reliable? is there a simple formula I could use? Maybe a mean of SPW and RPW?
