Unfortunately that looks 100% great
This is either due to flex somewhere in the frame or due to an issue somewhere in the math. If we want to see if it’s in the math a couple folks have created alternative versions of the math in excel or online, I think that those could be worth testing.
It looks like the measurements from the log above are:
