Direct measurement possible from an overhead shot? Video is mine.

New way of measuring cueball deflection squirt angle?

Interesting idea... hard to confirm the exact tip offset from that view, though.

Not more accurate, but maybe shows the CB's path more clearly?You really think that would be more accurate then just aiming the CB at a calibrated end-rail like just about every tester does?? Kinda tuff to accurately measure a blur. I'm assuming holiday boredom has struck.

Hitting a spot on the end rail doesn't tell the same thing?? More answers in search of a question. "My cue's blurs are better than yours". You play with a cue you figure out and adjust to its squirt. Does this 'blur measure' actually accomplish anything? I'm sure you'll find a pedantic way of telling me i'm all wet. You always do. Bye.
I mean the actual path (curve and all), not just the destination. Also, seeing the overhead comparison with the stick's direction can be helpful info.
Promise?

I believe only the angle between the 2 lines matter. Not tip offset. I could be wrong.
The difference with this is it’s visible with the naked eye and a regular camera. So it’s very intuitive what’s happening. Also it’s only squirt, as the swerve would happen later. (Or most of it, anyway)
I was randomly looking at my channel and this video popped up. I happened to pause it and saw the lines due to the fast shot speed and said to myself “wow, that’s squirt visible to the naked eye”.

Ps, that might be the best shot I ever made
I’m still proud of it a year later.

I put the picture in CAD and came up with 5.35 deg.
Parallax and fish eye distortion could be an issue with this. If the camera was directly over the CB at impact, it might improve those.
Revo 12.4. HARD hit. Max outside spin, as seen to make the "impossible bank" in the first post video.
@dr_dave @Bob Jewett how does this squirt angle compare?

A straight edge on the CB trail shows left edge to contact. The image squaring straightened that out?
That's about 5 inches in 5 diamonds. That's a lot -- seems like too much. One problem is that the shaft is deflected to the right. You need to overlay an image of the shaft an instant before tip-ball contact.
Stick is pointed at half facing. I'd go with that.
Agreed. That angle is much too large. I agree that the problem is the cue is in the "deflected" position (after the hit). For more-typical numbers, see:
“Squirt – Part II: experimental results” (BD, September, 2007).
