POWER RATING SYSTEM

Teams are grouped into divisions using various criteria (geography, enrollment, NYSPHSAA classification, etc.).  Division sizes in Section XI have ranged from nine teams to 21 teams.

A scheduling format must be determined and is a contributing factor (in addition to the range of competitive strength in each group and the size of each group) to the degree of success of the power system.

The power points are based solely on a team's performance and the performance of the teams it has played.  Each team's points are computed by taking that team's winning percentage and adding the winning percentage of each team it defeated and subtracting the losing percentage of each team to which it lost.  When there is a tie, the two teams involved either add or subtract the difference in the winning percentage of those two teams.  Points (and therefore rank) CANNOT be final until all teams in the division have completed their schedules.

Following the formulation of division and scheduling formats, each division must devise a seeding.

Procedure for Seeding:
1.   The Section XI sport chairman schedules division seeding meetings.
2.   Team information forms requesting pertinent data are completed by each coach in preparation for the seeding process.
3.   At the meeting, team information forms and division seeding forms are distributed for review.
4.   Each voting representative is expected to report on his/her team's anticipated strength and/or weakness and provide a suggested ranking for his/her own team within the division.  The order of speaking is indicated on each seeding form.  Following are the patterns:

# teams    rank from previous year

10            6,5,7,4,8,3,9,2,10,1
11            6,7,5,8,4,9,3,10,2,11,1
12            7,6,8,5,9,4,10,3,11,2,12,1
13            7,8,6,9,5,10,4,11,3,12,2,13,1
14            8,7,9,6,10,5,11,4,12,3,13,2,14,1
15            8,9,7,10,6,11,5,12,4,13,3,14,2,15,1
16            9,8,10,7,11,6,12,5,13,4,14,3,15,2,16,1
17            9,10,8,11,7,12,6,13,5,14,4,15,3,16,2,17,1
18            10,9,11,8,12,7,13,6,14,5,15,4,16,3,17,2,18,1
19            10,11,9,12,8,13,7,14,6,15,5,16,4,17,3,18,2,19,1
20            11,10,12,9,13,8,14,7,15,6,16,5,17,4,18,3,19,2,20,1
21            11,12,10,13,9,14,8,15,7,16,6,17,5,18,4,19,3,20,2,21,1

5.   Time is allowed for coaches to review data and rank all other teams (excluding their own) within the division.  Following the  speaking order, each coach reports his/her ranking of all other teams.
6.   Teams not represented are also ranked by coaches in attendance. The average of these rankings will be used.
7.  A subjective ranking is devised from the rankings by totaling the scores (numerical ranking) for each team.  The lowest score is the highest ranked, etc.
8.   Prior to the seeding process, it should be determined whether or not an objective ranking will be used.  Objective ranking is the ranking for each team within the division based on the previous years final standing.  For purposes of objective ranking:
    a.   If a team competed in a higher division the previous year, it will be placed a half position higher than its finish the previous year.
    b.   If a team competed in a lower division the previous year, it will be placed a half position lower than the previous year.
The objective ranking counts 25% of the final ranking.  Multiply the subjective ranking times three, add the objective ranking, and divide the total by four to determine the final ranking.  Ties will be broken by the subjective ranking.

If a team plays any part of its schedule, the games played will count and any unplayed games will be forfeited to the opposing schools.

Power Points

Division standings are determined by implementing the power rating point system.  At the completion of a division schedule, the following procedure determines rank:

Step 1
Assign the proper winning and losing percentage rating to each team based on its record.

Examples: 

(1)  Team X - record 5-2-1, winning raw score .71, losing raw score .29
(2)  Team Y - record 8-3-1, winning raw score .73, losing raw score .27

Step 2
Determine each team's individual point total as follows:
1.   For every win, add the winning percentage raw scores of the opponent.
2.   For every loss, subtract the losing raw scores of the opponent.
3.   Add each team's own winning percentage raw score to the total.
4.   For ties only:  determine the difference of the tied teams' winning raw scores and add the resulting positive or negative number to the appropriate team.

Examples:

(1)   Team A: 6-1-1 = .86 - Team B: 2-5-1 = .29 (difference = .57). Team B adds .57 to its total points. Team A subtracts .57 from its total points
(2)    Team A: 9-1-2 = .90 - Team B: 5-6-1 = .45 (difference = .45) .  Team B adds .45 to its total.  Team A subtracts .45 from its total.

Step 3
Set the final standings by ranking the teams in order using accumulated point totals.  Results may be curved to prevent the publication of a negative total for any team by adding a like positive number (100 points) to all scores.

Ties in Division Standings

The procedure for breaking ties in division standings (teams with exact power points):
1.   Head-to-head record breaks ties in point standings in favor of the winner.
2.   Compare record versus the highest finishing common opponent.  If the record is the same, continue to compare the performance of each team against the highest finishing common opponent in descending order until the tie is broken.
3.   If the tie has not been broken using common opponents, it will be broken by the team that beat the highest finishing uncommon opponent.
4.   If the tie is still not broken, the highest ranked team as determined by division coaches at the pre-schedule seeding meeting will be the team given the higher final division standing.

POWER POINT SYSTEM FOR 12 GAMES
(all other combinations are calculated: wins divided by wins+losses = winning pct)

STATISTIC REPORT FOR FIELD HOCKEY - League DII - run Nov 20, 1998

EXAMPLES:  East Islip - Won 9, Lost 3 - Winning Pct = .750

Note:  East Islip provides straight forward example with no complicating factors.

West Islip - Won 7, Lost 2, Tied 3 - Winning Pct = .78

Note:  West Islip illustrates the negative effect of ties with teams with poorer winning pct and of the compensating factor giving some reward for beating a team with no wins.

*Move decimal one place to the right and add 100.  This prevents the use of negative numbers, making for better comprehension of the standings.

STATISTIC REPORT FOR VAR FOOTBALL - LEAGUE DI- run Nov 20, 1998

EXAMPLES

Brentwood (same record as Northport) - Won 4, Lost 4 - Winning Pct = .50

Northport (same record as Brentwood) - Won 4, Lost 4 - Winning Pct =.50

Brentwood and Northport illustrate power point difference even when teams have the same win/loss record.

*Move decimal one place to the right and add 100.  This prevents the use of negative numbers, making for better comprehension of the standings.

STATISTIC REPORT FOR VAR BOYS SOCCER - League 7 - run Nov 20, 1998

EXAMPLE

Southold/Greenport - Won 7, Lost 5, Tied 2 - Winning Pct = .58

Southold/Greenport illustrates positive effect of ties with teams with a better winning pct (Mattituck and Center Moriches).  This also illustrates the power point difference with a win and a loss against the same team (Port Jefferson).  There is a compensating factor in the formula for teams with zero losses but one or more ties (refer to chart - Power Point System for 12 Games).

*Move decimal one place to the right and add 100.  This prevents the use of negative numbers, making for better comprehension of the standings.

(1) Preliminary (objective) seeding order

Notes:
Coaches do NOT rank their own team.
Ties in the final seeding will be broken by placing the school with the higher subjective
seeding in the higher seed.
