Testing Repeatability – Player Level

So yeah, this is just going to be a quick post to deal with some house-keeping. I’ve run a series of tests to check the repeatability of the various metrics I use. These are all done at player level, I plan on doing the same at team level at some stage. There will be no fancy Tableau graphics here! Just plain old Excel scatter plots. So here is a rundown of what I found. These may, or may not be useful for somebody.
