Quintic Consultancy released today two Youtube videos with excerpts from a Trackman evaluation study they performed with two Phantom cameras. The results were presented at the World Scientific Congress of Golf VI last year in March. Here are screen caps of the Trackman v. Phantom data contained in the two Youtube videos:

1597

An abstract of the study was published in the International Journal of Golf Science, Volume 1, Supplement, August 2012, pages S31-S33 . This table summarizes the results of the study:

I found this video, where they found a discrepancy in face angle of 5.5 degrees to be the most interesting one.......

Hadn't noticed that one. We can top it, though...

Mirrors what I seeing, on relatively centered squared hits the TM does a pretty good job, but lots of "math" telling you what happened on off centered, none square face angle hits and sometimes its just not correct, certainly questionable on what to teach a student in a lesson.

Really interesting!

From how much away from the CoG, can we say that TM numbers become inaccurate?

Does the Quintic study give a range of values?

Or do we have to wait for the Research-a-thon results ... :)

No; it was just an abstract and I've posted most of the interesting stuff. I'll email it to whoever wants it. Just PM me an email address.
