Looks like you got it right, but maybe number 5 has gradations tooJune 19 2017 at 1:06 PM

Response to cleanest PCP air source / supply
I think your table looks right, although one could argue the relative ranking of #1 and #2 (and of course #2 is not "air" anyways).
I think handpumping can also be split a bit too - different pumps have different filtration capabilities, and the biggest swing here is in the process the user chooses to follow - how many strokes in a session and the like . . .
To mean the real question is why do you ask? I spent quite a few years each with a Hill pump with Drypac (#5), then a tank filled by a dive shop (#1), and then a tank filled by a Shoebox with a good filter system before the unit but not after it (#4), and I can say this: I have never seen any difference inside my guns when I have torn them down for any maintenance or modifications. No signs of dirt, moisture or anything like that.
So in the end, if you do things "right" with each method, what difference does it make?
