That was my second guess ...

As I mentioned in the commit message, 270 is working fine for the setups I have
tested but I always wondered if that would be the case for every possible
setups/boards/modes.

Would you mind testing 90 and 180 as well with your setup ? I'll make another
pass on the different setups I have access to. Please stick to hs200 and drop
hs400 for this test. I'm still unsure if doubling the clock after doing the
tuning may affect the phase tuning ... lets keep that out of the way for now.
