This two confuse me all the time and the following are what I understand:
1. When I release my ball at the foul line (assume I'm a stroker and style is 10 10), my hand is completely behind the ball and roll forward.
in this case, the ball axis is parallel to the foul line, therefore the axis rotation 0 degree because axis rotation is measured the angle between the ball axis and the horizontal line.
in terms of axis tilt, it is 90 degree because axis tilt is measured the angle between the ball axis and the vertical line. the ball axis is also 90 degree angle as compared to the gutter - but this one I dont know the term to describe it.
2. When I release my ball at the foul line (again assume I'm a stroker and style is 10 10), my hand is completely at the side of the ball and rotate counter clock-wise (right-hander).
in this case, the ball axis is 90 degree angle to the foul line, therefore the axis rotation 90 degree.
in terms of axis tilt, it is also 90 degree as compared to the vertical line. the ball axis however is 0 degree angle as compared to the gutter.
3. When I release my ball at the foul line (again assume I'm a stroker and style is 10 10), my hand is completely at the side of the ball and move forward (right-hander), commonly known as spinning the ball.
in this case, the ball axis is 90 degree angle to the foul line, therefore the axis rotation 90 degree.
in terms of axis tilt, it is also 0 degree as compared to the vertical line. the ball axis however is 90 degree angle as compared to the gutter.
4. When I release my ball at the foul line (again assuming I'm a stroker and style is 10 10), my hand is half at the back of the ball and half at the side of the ball and rotate counter clock-wise (right-hander) ie 45 degree release.
in this case, the ball axis is 45 degree angle to the foul line, therefore the axis rotation 45 degree.
in terms of axis tilt, it is also 45 degree as compared to the vertical line. the ball axis is also 45 degree angle as compared to the gutter.
Now:
If someone asks tell me to increase my axis rotation, that means I have to place my hand more to the side of the ball.
If someone ask me to increase my axis tilt, that means I have to make the ball axis lessor angle to the gutter and larger angle to the vertical line. To do that I have to place my hand more to the side of and under the ball and rotate counter clock-wise.
Can anyone tell me whether I'm correct and pinpoint where are the wrongs.
