Looks like some of the regression tests failed. I can scale back this PR to be just the thumb rule or, with your guidance, dive into the other rules as well. Cheers.

@hoop71 Thanks for looking at it, but I think that the values are correct.

[hoop71]

Thanks! You and your team are awesome!

[oliviertassinari]

@hoop71 Alright, this seems like a safe change, let's move to a different problem, thanks for the feedback.
