Sounding reasonable to me
For everything rocketry in Australia

The carbon fiber sleeves we use have a similar fold, but we've never had an issue with it once it was wetted out and put on the mandrel. I'll have to keep your workaround in mind when we use the fiberglass sleeves.
I was surprised about the surface finish, especially with the peel ply. Did you wet out the peel ply after you put it on? We normally put the peel ply on, and then use the roller to fully wet out the peel ply so that you don't see any white air pockets under it. Just like when you wet out fiberglass.

I've always used this formula for getting a rough estimate of descent rate.
It's no longer on-line but available through the web archive. I think OpenRocket can also predict the descent rate based on parachute size, but I am not sure how accurate that is.
