So I completed the install of my new ClearVue CV1800 and am now tweaking my drops to get the 6" piping run all the way to the machines. I'm at the point now of connecting the table saw. I currently have a 4" port in the cabinet and a 2.5" shark guard port above the blade. I've been studying Bill Pentz's recommendations at the link below and in the example he cited, he went with a 4" shark guard and 5" port in the cabinet which resulted in a combined total of 32.20 square inches of cross sectional area in the ports. That's 4 square inches larger than the area of the 6" main pipe. So, my assumptions are below, hoping to get some confirmation that I'm correct before I go any further.

1. It's better to oversize the ports than undersize them.
2. Based on assumption 1, if I want to use the existing 2.5" shark guard port which results in a 4.9 square inch area, I should increase the size of the port in the cabinet to 6". This would give me a total of 33.17 square inches which is a better option than going with a 5" cabinet port which would result in 24.53 square inches making the area smaller than the main pipe. Am I thinking correctly on this?
3. If assumption 2 is correct, the 6" port in the cabinet would allow max air flow when I'm not using the shark guard during dado cuts and the extra 5 square inches added when using the guard won't have a noticeable impact on the system. I mean it's really only 1 square inch bigger than Bill's recommendation of using a 5" and 4" (32.20 square inches) and I can't imagine that 1 extra square inch is going to matter. Correct?
