Micro bubbles during brake bleed?

Just finished installing Goodridge G stop SS lines and flushing out DOT3 and replacing with DOT4 Motul. No problems with the install of lines and went through a manual bleeding process (both bleeders RR, LF, LR, RF) HOWEVER, on the final RF bleed, I'm still getting very small "streams" of almost foamy/micro bubbles intermittantly on the inner bleeder screw that I can see in the clear hoses I'm using for bleeding process. Every other bleeder runs clean.

I am pretty darn sure that I have bleed all the way from the master cylinder all the way through/past the ABS to the caliper by now. Is it possible I'm artifically introducing air into the system by way of a vacuum at the bleeder screw that makes it LOOK like I have air in the line? Also, NO signs of leaks at any of the connection points.

I've probably run close to a pint through just the RF keeping the M-C full through the process. The brakes feel fine and hard, stops hard and fast and no pull on braking. I'm thinking of running a couple of days and then "burping the lines to see if these small bubbles will eventually consolidate into some air I can purge. Since the RF is the last one to bleed, is it reasonable to just do this one? (I've bleed the others 3 times for the flush)

Any other thoughts??
