No, that moody diagram is pretty interesting. At a typical paintball reynolds number is right around 10E5

a 6 micron finish puts you on about the 2E-4 curve.

So, a bad finish would actually push things into the complete turbulence region. And a smoother pipe MAY incrementally improve the air turbulence in the barrel. Now, in most circumstances I don't think this will matter....but occasionally it could.

I think this explains some really interesting results I've seen on prototype barrels for the next generation eigenbarrel.
