Are you using an Adj gas block?

Never thought about that angle but it makes a ton of sense. Just barely put your finger over your garden hose and there isn't much there, about choke it off and pressure increases and there is much more resistance at your finger.

I have never used an adjustable gas block and don't really plan to at this point. Nothing against them but I haven't felt that I needed one.
