Richie -
Not the same around here without Jeffy! (I'm not as anti-Jeffy as one might think).

Maybe you should check to see who posted that video on youtube. Why do I care who posted it, was making my point I think the angle is poor for ME to draw a conclusion. Well it's from the guy who coined the term "drive hold" and he must think that video is good enough to demonstrate his point. Whether you care isn't the point I was making. You asked for a front on view and I posted one right from the originator of the " drive hold" theory. Maybe you could ask Kelvin why he would use a "bad angle" to show what Phil does with his iron "drive holding". He must think it's ok, he put it up as an example of what Phil does.

How did anyone get info from the article? The aroundhawaii.com site disappeared earlier this year. I even asked someone else to try to access it, but nothing, so it isn't my connection or PC.

Well, great. That means they've blocked the site to IP addresses outside the U.S. How kind of them.

Just tried a proxy and it works.

Tapio - Why do you believe that degrees per second is an incorrect measurement for rate of closure? What other form of measurement could be used? Not linear MPH. It should be distance related, not speed. The only part that really matters is about two feet both sides of the ball and at that area we see lot of differences between players.

(And anatomically, pronation/supination is technically an elbow movement.) No, it's not. It's forearm rotation and got nothing to do with elbow or wrist. Of course wrist turns also when forearm rotates, but it's not a word to use for wrist movement. Shaft flattening is real mark of left forearm proaction, shaft steepening is clear mark of left forearm supination. That's why I can't understand that Kelvin's early supination part. Maybe he still means early bowing or we see definition of early differently, but as far left forearm is parallel to the target line, supination will throw the club head outside of the hands and steepens the shaft

Then how would you state a number for the rate under your definition? Please provide an example. Most people think degrees per second.

Then how would you state a number for the rate under your definition? Please provide an example. Most people think degrees per second. I know most do, but it just makes no sense. First of all what we really want to know is how much CH rotates at impact area (1-2 feet both sides of the ball) because that's the thing that affects to the stability of the shots. Some player with high CHS will have maybe less rotation in degrees per second as their club moves through that area quickly, but they might have more rotation in degrees per inch than players with lower speeds. That's why the only reasonable way to measure it is degrees / inch (cm) And that's the real problem for coaching with these radar devices and also with other measuring devices. We got not real information from that area from CH and can't see if people are progressing with that or not. From High speed videos we can see huge differences between players, sometime between shots of the same player, but we got no numbers to compare.

Tapio-
Don't you want to look at how much the face angle varies relative to the clubhead path? That takes clubhead speed and the radius of the arc out of the equation. If I hear one more time that a driver has a higher ROC than an 8-iron, I'll scream.

Tapio-
I do agree with you, though, that degrees/inch makes more sense than degrees/per second if you are measuring ROC relative to the target line. But it seems to me face/path is what's important. Am I wrong???

Am I wrong??? Not wrong at all but not only that relation to the path, also path itself. Big view fools us to see it as an arc and it's not an arc when you watch it closer and from different angles,
