Has anyone actually tracked their expected value across multiple casinos?

I've been playing sweeps for a few months now and I'm trying to get a real picture of which casinos actually deliver on their payout claims. There's a lot of marketing noise out there, but I want to see actual numbers.

I started keeping a spreadsheet tracking my deposits, total wagered, and winnings across three different platforms. The variance is wild, but I'm looking at the math over a larger sample size to see if any of them are actually worth my time long-term.

My question: are you guys tracking this stuff? I know casino math favors the house by design, but some places seem to have better RTPs or at least more transparent terms around how their bonuses work. I'm specifically curious about which casinos publish their actual payout percentages or if anyone's reverse-engineered them based on real play data.

Also, I'm cautious about sites that bury their terms or make it impossible to understand the wagering requirements. That's usually a red flag for me.

Would be helpful to compare notes on what people have actually experienced with payouts and customer support when issues come up. Not looking for hype, just honest feedback on the expected value you're actually getting.

Anyone else nerdy enough to track this?
