I am still learning, so if I am mistaken please correct me.
From what I have been reading, It appears the reason for the lack of accuracy in a big jump. Is because some gasses get around the bullet before it gets in the rifling. Plus this causes a inconsistency in the pressure and changes the velocity. So if the bullet can hit the rifling before it completely exits the brass you would be good to go. Or at least consistent.
Shorter gap is better, but a short jump may be ok.
