Twist is not what makes a barrel accurate or inaccurate for balls.
Rifling geometry can sure have an effect though.
I used to make my own barrels back in Nevada years ago, and I made some to experiment with, having twists from 1-104" to as tight as 1-12" All were cut with .009" deep rifling and all were cut with grooves 2X as wide as lands.
All barrels were lapped to a very smooth internal finish and had no tight or loose spots.
There was no difference in group size at all. The 1-12" twist 50 cal still shot a ragged hole at 50 yards, just like the 1-76 and the 1-104 did.
Once a ball is stable, it's stable.
However the fast twist barrels would foul very fast, and the slow twist would not. So I would advise a slower twist for ball shooting just for that reason. As long as the bore is clean they were just as accurate.
But the idea of a tighter twist being inaccurate with balls is just not true.
The revere is true however.
If you try to shoot long bullets in a slow twist (say 1-56 or slower) you will have very bad performance, with some bullets even striking the paper sideways.
Gyroscopic stability if needed for any bullet, and long bullets being of 2X or more length to diameter, need a pretty good spin to keep them going nose forward.
With a 50 caliber barrel I made for a replacement for a 50-140 sharps I used a 1-22" twist with .005" deep grooves, cut with grooves as wide as lands, but with 10 degree angled sides. That Sharps came out very accurate when I was done.
The original barrel was twisted 1-38, and it was very tricky to get good accuracy from 500 grain bullets. The very long 750 grain bullets shot very poorly. With my 1-22" barrel the 750 grain bullets did very well.
I and the owner of the rifle were shooting poker chips with 750 grain bullets at 100 yards, where the old barrel would not keep them hitting the whole 24" paper.
So in a nut-shell, fast twists work with bullets and any twist works with balls as long as the grooves are deep enough to hold the ball/patch correctly and allow for enough thickness of the patch so it doesn't tear.
