I was confused; the thing that lingered at the back of my mind was that if we do the target extension for one direction and correct the interval in that direction, we should also correct the interval in the other direction, especially since as Jonathan points out the interval describes the full back-and-forth path…

I've updated the target to be 22ms based on my current interval of 450ms.

It's not pretty, but the quality is A or A+.

It's interesting to see the saw tooth pattern for the upload. This was
not the case when the target was 5ms, which I believe was calculated
based on a 100ms worse rtt.
