Glad to help, I have designed a lot of turbo system drains over the 39 years I did the job.
I think you have it covered. Like I said, but adding a comment, the turbo shaft inside the CHRA whips the oil being supplied to the CHRA in a foamy solution before it comes out of the CHRA.
You need a given size for the bubbles to travel thru the drain tube vs plug the drain tube with the bubbles.
When the oil cannot get out of the CHRA, the oil level builds up and then the slip ring on the turbo shaft sees oi.
Now you have a smokey exhaust with oil droplets at the exit of the exhaust pipe. Same thing happens with too much crankcase pressure on a turbo vehicle.
