In this video clip you'll see the ball skid through the heads, flare up onto a second axis then roll into the pins on another axis.
When you understand what's going on you can make much more sense of what might, at first, appear to be a confused blur. Try to look only at the white dots placed on the ball.
1- In the first second, just after release and as as the ball skids through the heads, you'll see a steady piece of tape: the ball is rotating around the bowlers initial axis (the PAP, Positive Axis point)
2- After this, the axis will start to move, migrate, from the PAP towards the grip line and you'll see the second Axis settle down (if only briefly)
3- Finally, the ball will move off that axis immediately prior to rolling into the pocket for a perfect strike. Notice, at this point, that the ball has flared so much it is almost rolling over it's initial axis (first tape).
This shows about where the tracer tapes are placed.
