If I were passing this much oil and not catching in my less effective can (saying your Provent is way better at catching than my AD1), I would be way down on dipstick reading at end of oil change interval. My dipstick always reads very close to full mark.
If you're concerned about the effectivity of your catch can, an option is to loosely place some steel wool into the can. Don't pack it, just pull some apart gently and set it in the can. This will create a huge amount of surface area for oil to collect on.
