Talk as much math as you want, it's called Poiseuille flow, I'm a mechanical engineer so this is a basic fluid dynamics concept. It absolutely does form drops. It may not be visible drops but on a molecular level it is, this is basic adhesion/cohesion. Every single restriction will cause a higher friction factor for the airflow, hence adding the larger boundary layer within the tube. It's not completely de-atomized to drops but with these intakes, it does add decrease atomization efficiency, enough to make a difference for sure. With a 95% certainty bet that if a different intake was used the 4 stroking symptom would clear up instantly.
Running lots of oil is a very old school way of thinking, which makes sense given your background. In your times' oil was not nearly as developed as it is now. Today synthesized oil technology has gotten to the point that you can even run 100:1 reliably all day long, which many do. Sure old conventional oils need the really heavy mix, but those oils are a thing of the past. Catching up with the times, a good quality synthetic can be run at 40:1-50:1 from the start, they're literally formulated for these ratios at break-in. I have about 400+ engines to prove it to, many with thousands upon thousands of miles as well. I have many china girls making 8+ hp running 10k all the time, WOT pulls, and the cylinders look flawless. What I'm trying to point out is the heavy oil mix isn't needed for break-in, in fact, it hurts long-time performance, you can run less oil at ZERO sacrifice of reliability nowadays. Sure your mix works for you, but I'm sure they would be running a lot better if you went a little leaner from the beginning. Can't even count how many engines I've seen fail from too much oil, its ridiculous.
