Instead of determining power percentage, I prefer finding a distance number (in feet) then factor in green speed, elevation and slope.  As all five meters on my putter are divisible by 3, and each scale correlates with some numbers on the other scales (except the 150 scale which I seldom use), using these calculations makes it easier, for me, to determine what power to apply. Here are some simple calculations to divide each meter in thirds...numbers that correlate with other scales are underlined.                
15-10-5
30-20-10
45-30-15
90-60-30
150-100-50
Taking this a step further, you can divide the scales by 6 (this does not always produce a whole number) which takes out even more of the guess work and allows for more accuracy.   And by doing so, notice how the 150 scale begins to correlate with other scales and how 15 feet appears in all but the 150 scale, making it a good reference point.     
15-12.5-10-7.5-5-2.5
30-25-20-15-10-5
45-37.5-30-22.5-15-7.5
90-75-60-45-30-15
150-125-100-75-50-25

This is my way of dividing the meter, is easier for me to do the math and it helps me with feel.  It is not necessarily the distances the ball will travel, it does not factor green speed, slope and elevation nor does it correlate with avatar movements discussed in other forums.  In the end, its all about practice and getting the right feel.

Whether or not a person condones quitting, sandbagging, remaining in a tier longer than is warranted, advancing quicker than others think you should, the reason this happens is because the system allows this to happen.  And if you don’t agree, you need only look at the way our scoring average is calculated.  So until there is a new system, especially now that we can wager credits with other players, it is more important than ever that we understand how the system works, to ethically play within its constrains and act accordingly.

There continues to be criticism of those that remain in a tier longer than warranted, those that advance quicker than is obvious, those that seek refuge in new accounts and those that seemingly take advantage of this game.  I’d like to believe most of these players are not cheating…but for those not following the terms and conditions, we need only look toward how our scoring averages are determined as the culprit.  With a Handicap Index that is based on peak performance, supervised by a club, and takes into account slope and course ratings, it allows for fair competition.  In our system, players are allowed to quit games, post only their best scores, apparently gives the same weight to 9 hole rounds as 18 hole rounds, and gives no adjustment for the posting of unusually high scores to prevent Sandbagging.          

Many of these ideas have been kicked around before but bear repeating.  To level the playing field, I believe these suggestions should be implemented to determine our scoring averages.                 

1.  Use all scores, including incomplete rounds.  
2.  Averages would reflect peak performance with little or no weight given to average play.  
3.  18 hole rounds would carry more weight than an a 9 hole round.         
4.  Adjusted to reflect what tees are played from, wind conditions, green speeds and the course Par rating.        
5.  Only tournament rounds would affect scoring averages.

There are improvements needed in our quasi handicap system and it is important to know how the tier system works so you can survive around here.  In a real handicap index, players who are an 18 can compete right along side a 7 and both have an equal chance to win.  Now, for example, take our Pro Tier...all players participate against one another, whether you are at the high end of that division, hence not as competitive, or close to becoming a Master...and unlike a true handicap index, there are no allowances for the large gap in scoring averages.  This can be frustrating, but it can also give you the motivation to get better.      

The good news, and I have only been here since May, is there have been lots of changes...and some even for the better (0;\  Many changes, I am sure, have come at the behest of people who make their thoughts known...that is what these blogs and our forums are all about.    

Who knows, maybe someday we will have some true handicap competitions...that is, where any player can play against any other player and actually have a chance to win (wink).  For now, it is what it is...as always, the guys who know their way around are the ones who win and more power to them.
