Can the roll phase be the culprit?

[AZBowla]

Don't forget to factor in the lane conditions too. If you're doing mostly open bowling like me then there's no telling when those lanes were oiled last. My Marauder soaks up what little oil is left like a sponge so after the first couple of games it's like a desert out there. If you have a lot of revs and find you have to go coast to coast just to hit the pocket then try a different line and put less revs on the ball or you'll just be burning off all the ball's energy, resulting in soft pocket hits. That's been my experience at least.

BOWL1820-Thanks for the diagrams and video! So if i'm to understand,the midlane read is actually the hook phase?

Zothen

Yes, you are correct.

Funny isn't it? Anyone else fooled into thinking the roll was the hook?

At one point, back in the dark ages, bowlers used to refer to it as skid, roll, and hook, as if the ball had to get into a full roll before hooking. The ball motion studies proved the hook was actually the transition from skid to roll.

The length and area of each phase will be different for each bowler and each style. Funny? Hardly. It creates frustration.
Speaking of frustration, you're in for more. In post 10 you stated you were going to change your release to get more revs less skid. Revs increase the push past the oil, hence more skid. If you are only just confusing revs with axis rotation then yes, a higher rotation angle will decrease the skid phase. That's why high speed, high rev crankers use a 90* axis rotation, to get that harder bite further down lane. But a consistent, high scoring release can be had with low revs, 30-45* axis rotation and a more gradual hook. Remember, it's angle into the pocket that creates the highest strike potential, not how it gets there.

Actually, there are two transitions.

The first transition is from skid to hook.

The second transition is hook to roll.

What's the part about spin time?

What's the part about spin time?

That's referring to putting the ball on a determinator and the checking the spin time on it.

Hook phase and spin time aren't quite the same thing.

According to Mo (some time ago) the hook phase ends when the migrating axis point reaches the line between the Pin and PSA.

The Spin time is how long it takes the ball spinning at an unknown (not commonly known) RPM on the DeTerminator to migrate from the "neutral position" to the PSA.

Not exactly apples to oranges, but at least different types of apples.
