Do not be concern about "pop" time, it creates one handed "lazy" catchers who cannot block the pitchers curve ball. When you "warm" up - practice catching the thrown ball on the heal of your mitt. This allows a quick transfer into the throwing hand. Infielders also should practice.
Question: do you use a Easton catchers mitt?
I'm not sure how it creates "lazy" catchers per say. I am more focused on blocking the pictures curve ball then throwing the runner out if I have to choose between the two. and I do not have an Easton mitt, I had All Star
