ScottHope:
They are just markers to show you how much power you have selected...
...but you won't see these percentage marks. I have just added them to this image to make things a little clearer.
And do remember, the % is NOT a linear progression
As illustration, let's say you have a 300yd driver (just using that for ease of number)
If you hit it at 90% don't expect it to travel 270yd - it will fly less than that
That said, according to a previous post I recall, a mod did say that the putter would be THE MOST linear (10ft would = 10ft on standard green I think - but don'the quote me lol)
From what I remember and a little experience
Hit'em straight

Edit - thanks bubbs, thought it was something like that :))
