I really don't think blind squonking applies to RBA's. Yeah, you can do it with A7's or the side venting ones (if you cover the hole with a finger tip) but you really don't need to. Use time. I think I read this somewhere on here, but it may just be the voices in my head again.
What has worked well for me is taking the RBA, removing the drip tip, then squonking until you see that enough juice has come up to really saturate the coil. Then stop the squonk. Make a mental note of how long you pressed on the bottle. BTW, make it one continuous squeeze - not a bunch of quick pumps. Gravity and a little vacuum created by the bottle will suck the juice back into the bottle. Then your good to go. Do this with both a full bottle and once again when it is half full or less.
It varies on how full the bottle is with liquid. My theory is the more air there is in the bottle the longer it takes to saturate the coil because air compresses more easily than a liquid, and I'm sticking to my story. I've found that the duration of the squonk really doesn't matter between my three different models of RBA's (reomizer, A7's, ERA). A full bottle maybe three seconds. A less than half full bottle maybe up to five seconds. I don't think about it much anymore. It's become kinda automatic, like breathing. Taste goes flat or gets yucky - squonk for 3 to 5 and everything is good.
All this talk about RBA's is good and I enjoy reading all of them, but I really want to know about the super secret upcoming mod codenamed "P68" at Reos HQ's*. Can we inject a mole or possibly extort Wayne with some Columbian hookers?
* I nominate that the P68 be named the NorthKorea (something to do with being vaporized...).
