Don't understand my GHIN index

[sonicblue]

I know the math on the handicap, and I finally am logging scores in GHIN. I have a set of scores, and can't figure out why it's yielding the index it is. This is straight off GHIN as it's displaying my scores.

Score - rating - slope - diff
89 - 69.9 - 128 - 16.9
88 - 70.7 - 130 - 15
84 - 68.8 - 120 - 14.3
79 - 68.3 - 118 - 10.2
82 - 71.4 - 132 - 9.1
82 - 71.4 - 132 - 9.1
81 - 70.4 - 135 - 8.9
82 - 72.9 - 135 - 7.6
77 - 69.9 - 128 - 6.3

With only 9 scores posted, it should be averaging my best three, which I sorted to the bottom here.

6.3+7.6+8.9 = 22.8
22.8 / 3 = 7.6
7.6 * 0.96 = 7.3

GHIN is telling me a 6.0, which says it's usually just one score. What am I missing?

My guess is you only had 5 or 6 score in the computer at the time of the last revision, with only 5 or 6 scores it will only take you best score.

To Be Used
5 or 6 Lowest 1
7 or 8 Lowest 2
9 or 10 Lowest 3
11 or 12 Lowest 4
13 or 14 Lowest 5
15 or 16 Lowest 6
17 Lowest 7
18 Lowest 8
19 Lowest 9
20 Lowest 10

Mind you I am on the RCGA system and we don't have revisions, our HDCP's are calculated the minute we enter them.

Ah, you're probably right, I forgot GHIN doesn't go real-time.

The score list on GHIN should have an asterisk in front of each score that is being used in the current calculation. That might give you a better idea of where your index is coming from.

I don't have/keep a GHIN index...but I use this website and it works great for me.

That's the one I use too. Really simple, and easy to use, rather than dealing with all the offical GHIN stuff.

Aside from the cost (a very modest $20), what's tough to use with GHIN? You figure out your ESC score, which you'd have to do anyway, and enter it. If the course isn't on the lookup tables, you just enter it manually.

Unless you actually want an official handicap which is usable for competition purposes.

I don't have an official number this year, and I miss it. I'm getting mine again next year and curious to if its going to move. It should go down as I've gotten better this year.
