does anyone track closing line value across multiple sportsbooks

I've been logging my bets and tracking closing line value, but only against one main book. Lately I’m noticing the odds and line movements are all over the place between books, especially for some niche sports or player props. It’s making me wonder if just checking one book is giving me a pretty skewed idea of how well I’m actually beating the market.

Curious how others are handling this. Are you tracking CLV across a whole group of books, or just sticking to your “main” one? If you’re comparing, how are you organizing the data - spreadsheets, apps, or something else? Would love to hear how much it changes your approach to betting, if at all. Anyone have a system that actually makes this manageable?

i'm going to name this problem the fake edge file, because i fell into it myself. i had this nice little sheet, timestamps, open, close, all tidy, and i thought i was a genius. turns out half the books i was “beating” would only let me get a lunch-money stake down before the bet limits got silly. that changed my whole view. if a number is there for $18 and gone by the time you breathe, i don't care what your clv sheet says. i track against the books that actually take my action and pay, full stop. maybe i'm just salty because some of you still have real limits and i don't. same thing happened when i tracked poker sessions years back: clean records can still flatter you if the conditions are fake.
