sweetmiffy: If the meter speed works in reverse, ie 4.5 is slower than 3.5, then does that apply to all the attributes.
First of if this is a tad confusing to you then to a noob it may be kaleidoscope time, and so a good point IMO.
A simple explanation stating that the higher the number the better, no matter what the attribute being described, may help immensely. Saying that I do like the numbers as these lend themselves to more exactness overall IMO (hopefully).
sweetmiffy: So...Does my level 59 set have more or less precision than the VR Forged set?
The Nike VR set has the highest number for this, and therefore the Nike VRs have the most precision of any of the above.
Separately if you are considering new irons only the L90 R11s will really allow you to compete against the elite to the fullest. Not saying the others are bad and the meter can seem a little scary at first, but only at first for most. You don't need to change at all until Legend though.
