No seriously guys, this is tough. I can only say that any of you that haven't fired a springer have no idea how temperamental these things can be; at least the two that I have owned.
This is the Walther Terrus. Ammo is the 8.3 gr RWS Superdomes. The range is 25 yds. shouldn't be that tough right ?
Well it took an hour of practice to produce this group from a rest

My problems I was able to identify? Well for one putting my pinky under the grip (like you do a single action). Believe it or not, that is enough to toss the round. I'm thinking it's prevending the muzzle from rising, wasn't even aware I was doing it. Same thing, putting my left hand under the grip hand.
Also finding the balance between how much pressure I'm putting against my shoulder vs pressure on the grip. Yes I'm serious.
You also have to place you hand in the EXACT same place on the fore stock. Don't cup that hand or again you got a flyer....

I found it helpful to mark a spot on the stock to terminate my grip in the same place. That worked great, but I hope I don't mar that beautiful stock

So there it is. You would have to go through this yourself to comprehend how NCG can shoot these things offhand.
