A couple reasons why I hate doing port work after others

I always tube first so I can port over till I just touch the tubing.

What size cross section you getting with tubing ?

I was also wondering, I was watching a Eric Weingartner video and he said he finds peak flow and the short side csa generally correlate Eg. 300 cfm and 3.0" short side area do you notice a similar correlation?
