Recently I found my Flow Control behaving oddly, and the only posts I've found anywhere that appear to addressing the same issue is "Flow Control Issue with ECM Synchronika" thread here (now closed for comments).

Very good point! Would we not see the effects of a dulled burr in the shot? I'm guessing consistently channeling no matter how fine of a grind? Might be easier to see in espresso vs coarser pour over/brew? Edit: Could this be the reason that a lot of people

thanks. got it down to about 8.7bar. clockwise tighten, counter lowers. a bit lower than i hoped, but gonna try stick to this settings for awhile. pulled once, flow ramps to 8 and brews beautiful. reason is with my ssp shots dont flow well.. even with manual preinfusion until initial drip shots will continue to rise in pressure
