Added a timestamp column to the spreadsheet three seasons ago. Not something I'd thought to track before. Assumed the hour was irrelevant to the analytical quality of the decision.
The data disagreed.
My bets placed between 6am and 2pm: CLV positive at the expected rate. P&L consistent with the edge the model produces.
My bets placed between 9pm and midnight: CLV slightly positive but noticeably lower. P&L positive but below the daytime rate.
My bets placed after midnight: I have eleven of these across three seasons. I didn't know that number until I added the timestamp column. The CLV on those eleven: negative. Every single one.
The decisions felt defensible at the time. I had reasoning for each. The reasoning was apparently worse than it felt.
The pattern I didn't notice from the inside: I was doing my primary analysis in the mornings, identifying qualifying selections, and then sometimes revisiting the markets in the evenings. The evening revisits occasionally produced additional bets that weren't in the morning's output. Those bets were performing below the morning selections.
The late-night eleven were the worst version of this. Analysis done during a period when analysis is genuinely worse, feeling like the same quality as morning analysis.
The question: does anyone else have timestamp data. And for those who don't, what hour do you think your bets concentrate in and do you think that's the right hour.
