That would be interesting to group your findings/issues on RPU in a dedicated topic, because I don't think the logic changed recently So it's an interesting investigation to make.
6.12.90 -> bad
6.12.45 -> bad
6.12.22 -> bad
6.12.11 -> bad
6.12.5 -> bad
BUT 6.12.2 is GOOD! Almost there!
edit: now 6.12.3 is also good. Getting close…
edit: since 6.12.4 is good, then the issue is within 6.12.5. Investigating now.
