It's not to do with clicks. That's a side benefit and it's not that big of a deal.
If you put in a scope height of 3cm (which is almost on the barrel for a 56mm scope) you get 8 1/4 MOA clicks between 50 & 55. If you put in 9 cm for a height then you get 5. No one is really going to start with 3, so the actual gain between say 5 (which is 7 clicks) and say 15cm (which is 4 clicks) is only 3 clicks for a 10cm move.
It makes much more of a difference at closer ranges.
As said it doesn't change your tracjectory, but changes how you look at it. But closer in the angle of difference is much steeper, further out the pellet is more inline with the line of sight.
Stick it in chairgun and it will show you all this. But there's no point in putting a scope where it mucks up your position.
