You sound similar to me when I release the ball.
Your probably tracking close the fingers and thumb
all your shots.
Its just that on the dryer shot, the
ball flares away from the holes more and faster.
When on the wetter shot it doesnt flare as much
and stays near the holes longer. So you see it clipping them.
The weaker equipment would do the same. It would be a lower flare
and the track didnt migrate away from the holes much.

What you wrote sounds just like if I wrote it.

I got that same mark on the ball that you did.
Though I stopped getting it years ago when they
changed from wood to synthetic lanes.

I believe part of the reason for where its tracking,
is from coming up the back of the ball too much.
and when you get right more, its like rolling the ball
end over end. Which would keep it he track close to the holes.

I think what I'm trying to say is the thumb is coming out at 12:00
and the fingers are staying at 6:00 and not rotating to 3.

Also
Ball layouts with the pin above the fingers have
helped me alot. When ever Ive had a pin below the level
of the fingers I track even closer to the fingers and thumb.

This happend real bad with my black widow.
I wreote this in my BW review-
Layout #01-
60 degree layout Pin placement is 5" from the PAP,located below the ring
finger. Mass Bias placement is 3.25" right of the centerline, below and
to the right of the thumb hole. It's similar to the #2 (All Purpose)
drilling on the Black Widow drilling sheet. No X hole.

Ball with Layout #01 Review
This was the wrong layout for me on the Black Widow.  With my high track
this drilling caused me to track over the finger and thumb hole
regardless to how I released it. This happened to me once before with a
MoRich Labyrinth and a similar drilling on it. All most no reaction with
the ball on wet or dry condition. Very little flare about 1"-2". Like
the Labyrinth this ball needs to be drilled with alot of regard for the
pin safe zones if you have a high track! Follow the drilling sheet.
