Don't think of the bowl.com videos as gospel. The shot plays different everywhere and depending on the lane surface and machine may not even remotely look like what it is supposed to be...
just play what the lanes give you. You can not "make a shot work" like on a THS.
in practice throw a slightly slower shot up 5, up 10, and up 15 and then pick your best shot to get to the pocket.
I wasted 4 weeks trying to play the pattern how you are "supposed" to play it.
Don't get discouraged and don't try to be a superstar.
The lanes usually play you.. you usually don't overpower the lanes.
