I agree with both Erik and suberjc on this. I've had and still have rifles that string shots laterally at every distance with loads that don't suit them Sometimes, the verticals are fantastic.
Yes, team coaches pick shooters who have the stamina, mental attitudes, and equipment to consistently shoot small verticals at long ranges. But, they also know when a lateral shift was not induced by the wind and was down to the shooter or the kit and people who produce them aren't picked either - it may just take a few shots more for the coach to realise what's happening while verticals stare back at you from the plotting sheet pattern. Top wind coaches can read amazingly small and subtle changes in my experience and while they get readings wrong, they do so a lot less than most ordinary mortals.
