Outside help/Club distances during round

I just read the post on lead tape during a round and it got me thinking about an article/quick tip in this motnhs' Golf World with Sandy Lyle.

The tip is to basically to put some tape around each club and write on the tape your distances for a full swing, 3/4 swing, 1/2 swing and grip down swing.

Is this legal ?  and could you carry a card round showing your average distance or is it deemed to be outside help in some way ??

You're probably right, I hadn't thought about the course yardage books they carry.  I just wasn't sure if you could specifically document club distances or whether that it was use from memory only.

Nothing wrong with you knowing how far you hit each club with a full, 3/4 and 1/2 swing.

Most of my scoring clubs I know in my head how far these distances are, but I have a piece of paper in my yardage book with them written down.

And it's not unusual for me to have to alter these distances two or three times during a season.

Don't know why, maybe I'm making a better contact with the ball, or even using a different golf ball.

Thanks, you learn something new every day

What about a tips book showing quick fixes for things like playing downhill lies, ball below feet etc?

AS GPSs are allowed I can't think of anything to do with yardage that can be seen as illegal. I personally don't agree with GPS's in competition (though I've listened on the tee). I think Russ is lucky if he knows how far his shots are going. I don't.. I go through phases where ...my full 9 iron can go 120-150 yds depending on my strike. a 20% difference is disconcerting.
