It isn't that big of an adjustment.
I had 12U kids pitch an entire scrimmage from a 46' plate because it "looked" right. The bases were at 65' too that was what caused the confusion. 90% of the adjustment is made in the first three pitches. The last 10% takes longer depending on how much change has to be made to get their movement pitches exactly where they want them.
I've also seen 14B and Rec pitchers work from that distance and the extra three feet doesn't make them noticably worse.
On a straight fast ball 50 mph the difference in drop height is only 8" lower on 43 ft vs 40ft.
