Oil Restrictor Discussion

This is one subject that seems to confuse me based on the differing opinions.

I was reading the Butler website and on the Johnson lifter page, it says " they recommend a .020 or .040 restricted push rod.

Why would you ever restrict oil with a hyd roller?

I do understand why on a solid roller but there are so many different opinions on how much it should be restricted.
