Was having clogging issues so I thought I'd replace and get the mythically good capricorn tubes. This is a good sign that I needed to.

You don't really use pressure advance in bowden systems because the bowden system is flexible enough that it actually negates most of the advantages of pressure advance. As the pressure increases, the bowden tube itself stretches lengthwise. This has little or nothing to do with the interior bore of the PTFE tubing. The reason you are increasing it so much is because you're overshooting due to the length of the tubing, not the internal diameter.

We're not comparing Bowden vs Non-Bowden here, regardless. We're comparing generic PTFE bowden, to "Capricorn" bowden anyhow.

So you've managed to argue the completely wrong thing to begin with, AND you were wrong on the thing you argued. Congrats.
