450b ptp mode 55% downlink max

I installed a temporary link yesterday consisting of a pair of 5Ghz 450b radios. When operating on a DFS channel, the maximum downlink data I can configure is 55%. Is this a regulatory “feature”? In the 450 guide, 75% is mentioned as the maximum configurable for DFS frequencies.

This link is running 22.1.1

It’s 3am, so I’m probably not thinking correctly; but couldn’t you just change which end is Backhaul Master and Backhaul Slave…

I very well could, but my question is really intended to determine if this is a bug or a regulatory limitation - just so I know.

Just ran into this issue today under the same circumstances. I’m also wondering if this is by design.
