Among all the tourney highlight and mushy tribute videos for Bo Mee Lee, I came across a unique one, where her driver swing met the computer age on 3/19/2015: www.youtube.com/watch?v=r83kJjqsqzQ
I don't know Japanese, but there were three items that caught my attention:
2:00 - I assume 45.2 m/s (meters per second) is her clubhead speed. If my math is right, that's 101.1 MPH. I wonder how that compares to the median speed on the LPGA tour.
2:25 - What slicers need to do more often...the dropdown path on the downswing.
2:50 - A carry of 233 yards doesn't seem like a lot, but she gets a lot of rollout. I've seen her drives scamper between the 260 and 270 graphic markers that the JLPGA broadcast will overlay on the fairways. She plays the Srixon Z-Star ball.
Obviously, she has a totally different swing and the oomph she puts into it is much more evident. One might assume her swing speed is as much as BML'S, but no, it's less at 42.7 m/s, or 95.5 MPH.
This guy also posted videos of the same analysis using irons for both players. I don't know what iron was used in each case, but BML had more speed with that, too. One visible difference was that BML took a divot and Erika picked it clean.
It looks like Bo Me has more extension on her backswing. She also hits down the line longer. Erica has a very slight reverse pivot as her head moves slightly forward, at the top of her backswing. She also comes inside a little quicker on the follow through.
I believe 100 mph is above average swing speed. Anyway they both have great swings.
Obviously, never seeing them play....I would think both would be about 95 MPH take or give a MPH. If indeed BML is at 101 MPH (I question this on a consistent basis) she'd be one of the longer player if she was a LPGA member. But stats can be deceiving....Ariya is at #18.....but she seldom uses a driver.
BML has a tighter swing....Erika is way past parallel and in some...this has an opposite effect....losing distance.
That's a good chart...there's also a video of a Japanese male whose driver speed was 113.4 MPH with a carry of 262, which is in the chart's ballpark. I heard Greg Norman say he used to be 132 MPH...I don't know if that was during his persimmon days or after he switched to metal.
If indeed BML is at 101 MPH (I question this on a consistent basis) she'd be one of the longer player if she was a LPGA member.
