I suppose it depends on what level you are shooting at.

There's a reason why the majority at the top of FT, HFT and BR weigh pellets.
Yes, but you're talking about 0.5gn spread which can make a difference,
if you say 0.5gn =30fps then 0.01gn = 7 inches per second, I doubt many rifles are that consistent shot to shot.

There's a limit at which such things cease to have any measurable influence.
