Avaya Golf Leagues Rules



RULES

 - USGA Rules of Golf apply except as modified by local rules
   and with the following additions/exceptions:

 - Legacy Ridge has changed their tee box colors in 2013, as a result, below
   are the tees everyone should be playing from:

   Men with a handicap of 8 or lower play from the Black tees at Legacy
	Ridge and the Blue tees at Thorncreek
   Men with a handicap of 9 or greater play from the Blue tees at Legacy
	Ridge and the White tees at Thorncreek

   Ladies at Thorncreek will play from the Red tees.

   Ladies at Legacy Ridge:
   	Women play from the White tees on all Par 3's and 4's.  No matter 
	where there WHITE tee markers are placed on the par-5 holes (#3 
   	and #6) on Legacy Ridge, ladies on the league will always play from 
	the front groomed tee box of the 4 back tee boxes.  Reason being that 
	those two holes are brutally long for the ladies, and this would make 
	the holes more competitive.  

 - Penalties - If during a round of play, a question arises regarding
   assessment of penalty, the circumstances should be noted by
   both players, a provisional ball as well as the original ball should
   be played out for the remainder of the hole in question, and a
   report along with the scorecard be made to the league secretary.
   The matter will be resolved through the league secretary.

 - Temporary greens - When in use, take a maximum of two putts.

 - Obstructions - player is allowed relief for obstructed swing or
   stance only, from nearest edge of obstruction to ball, or two
   club lengths no closer to the hole.  NOTE: Objects defining out
   of bounds are not obstructions and the ball must be played
   as-is, or moved with a 1 stroke penalty.

 - Out of bounds or lost ball is treated as a hazard, where
   you can hit your next shot from the point of entry, with a one
   stroke penalty.

 - Players are allowed to use a putting ball on the putting green.
   The putting green does not include the fringe, and a ball may
   not be lifted and placed until it is on the putting surface.

 - To speed up play, a player may, under one stroke penalty, move 
   a ball from anywhere the rough is uncut to the first cut. regardless 
   of distance.

 - Players may improve their lies in their own fairway only by moving
   their ball up to six inches no closer to the hole.

SCORING

 - A total of 42 points shall be awarded as follows:
   There are effectively two matches played by each foursome.
   The lower handicap players on each team play  against each
   other and higher handicap players on each team play  against
   each other.   Two points will be awarded for each hole won by
   "match play" using handicaps for each match.   For "halved"
   holes, one point for each opposing player will be awarded.
   Thus a total of four points are awarded per hole.   Six points will
   be awarded for low combined team net score.

 - If there is only one player that shows up, then that player will
   play a match against each opponent on the other team, best
   ball handicap for each hole.  The single player will compare
   net score against the lower net score of the other two
   opponents for the final six points.

INFORMATION ON HOW HANDICAPS ARE CALCULATED

	#1) 
	for each round a golfer has played, calculate an adjusted round score (AS) ... calculating an AS
	is pretty straightforward .... add up all the individual hole scores for a round with a maximum score per
	hole based on the players current handicap .... for example, 
	
	player A -- handicap 6		scores: 5 4 6 9 3 4 5 11 5 ---> score = 52  adjusted score = 46
	the max hole score that player A can take with a 6 handicap is a 7 so the 4th hole score
	or 9 becomes a 7and the 8th hole score of 11 becomes a 7

	player B -- handicap 16		scores: 5 4 6 9 3 4 5 11 5 ---> score = 52  adjusted score = 50
	the max hole score that player B can take with a 16 handicap is a 9 so the 8th hole score 
	of 11 becomes a 9

	the table:

   golfer handicap	max hole score
   ---------------	--------------
	0-4		double boggie
	5-9		7
	10-14		8
	15-20		9
	20+		10

	#2)
	for each round a golfer has played, calculate an differential score (D) .... calculating a D score is
	done by the following formula

	D = (AS - "course rating") * 113 / "course slope"

	the course rating is usually given in terms of 18-holes and for our league we divide by 2 for 9-holes 

	player A -- AS = 44, played thorncreek men's tees front (rating = 36.4, slope = 126)
	player A's D = 6.81

	player B -- AS = 44, played broadlands men's tees front (rating = 35.6, slope = 122)
	player B's D = 7.78

	even though both players shot the same score, thorncreek is rated harder and therefore player A's D score
	is lower than player B's D score

	#3)
	handicap is determined by taking a number of D scores and averaging them and then taking 96% of it ... the
	number of scores used is determined by the number of rounds played ... the maximum number of rounds used is
	most recent 20 

	the table:

	# of rounds	# scores used
        -----------	-------------
	1-6		best 1
	7-8		best 2
	9-10		best 3
	11-12		best 4
	13-14		best 5
	15-16		best 6
	17		best 7
	18		best 8
	19		best 9
	20 		best 10

	player's -- D scores --> 6.81 - 5.24 - 10.32 - 3.43 - 8.60 - 9.43 - 18.32 - 7.68 - 7.23
	this player has played 9 rounds so we need to get the best 3 --> 3.43 - 5.24 - 6.81 ---> 5.16
	and 96% of that gives a handicap of 4.95 or 5 !!!!

	now, what if this player plays another round and shots really badly and gets a diff of 23.34 ... 
	the handicap doesn't change at all since 10 rounds still average the top 3 scores ... this
	hopefully explains why a handicap doesn't automatically go up when you have a bad round

	now, what if this player plays another round an shots lights out and gets a diff of 2.34 ... the
	handicap goes down !!!!!  best 3 are now 2.34 - 3.43 - 5.24 --> 3.67 and 96% of that gives
	a handicap of 3.52 or 4 !!!! ... this hopefully explains why a handicap can drop drastically when
	a good round is shot

	hope this helps
