Easy way to calculate swing speed

[Chas]

Step 1
Hit the driving range. Drive 10 golf balls. Note the number of yards each ball travels before initial ground contact. Do not measure rolling distance. Bring a partner along to spot your balls so you can concentrate on driving.
Step 2
Disregard the extremes. Eliminating the longest and shortest drives ensures that undesirable factors such as wind are not skewing your average distance.
Step 3
Find your average. Add the remaining drive distances and divide the total by eight. This will give you the average drive distance yardage.
Step 4
Divide the average yardage by 2.3. This number represents your average club head speed in miles per hour, according to the book "Science and Golf III." If 195 is your average drive distance yardage, 84.7 mph is your approximate swing speed.

That comes out just about right for me.

This is amazing. Mine came out to 98 mph which is what I got at the Bridgestone ball test (actually 98-102).
