Proof that Leslie's 2022 CYA is weak

[Rocket J Squirrel]

I put in so much CYA this year trying to raise it from 30 to 40 that it should have hit 90. Here are 365 day results from PoolMath. The reading of 50 happened once during the year, so may be test error.

Now that is just sad! Anyone else use Leslie's brand had this happen?
