Vacuum Hanging All Day Stretcher ADS problem - big purple glans with low weight

Been doing noobie routine for 3 months and have decided to advance. I’ve been trying to vacuum hang and use all day stretcher and am running into this problem of big purple glans every time I do it. I am using just 1 pound hanging, and very light force on the All Day Stretcher (ADS) while I try to get this right. My glans becomes big enough to fill the glans cap and purple. It’s NOT blue, and it’s not cold, and doesn’t hurt. But the most I’ve kept it in there it 10 minutes because I’m scared something bad will happen. I ordered a new cap and new silicon connectors as I think the original silicon connectors were too tight maybe, but the same problem is coming up.

I will start taping soon, but then I can’t see if my glans is big and purple, so is this a proper solution? Is the tape meant to prevent the glans from becoming purple and engorged, or is it just to prevent surface level injuries like blisters? Should I wrap the tape tight so as to prevent blood from engorging the glans? Or just snug so that it’s a barrier between the suction and my glans? Side note, my glans does get big and purple when erect, so maybe this is my natural state, but during simple light hanging, I don’t think this should be happening. Thanks!
