Default FTP fps Consistency

Out of interest I've started looking at consistency of my FTP over the chrono ( I like to add doubt to everything I do )

From a 200 bar fill to it going off reg at 100 bar I got 128 good shots with a fps spread of 20 which I thought was good considering the volume of shots with a new tin of unweighed, unwashed pellets.

I guess my question is and everybody's experience will be different but what is deemed good and what is acceptable as fps spread and how many shots would you normally take as a reference as I'm pretty confident you'll not shoot a full string to check the rifles spread.

For instance if I pick three random 5 shot strings out of my full string I'd get 7fps spread on one, 14fps on next and finally 9fps on last

Just interested really and I know a few fps here and there is less important than technique, wind etc but curious ...
