Ten Goal Limit (TGL)
 


 A modification to the rating system encourages sportsmanship by disregarding
 goal margins in excess of 10. A team favored by more than 10 goals need only win
 by 10 without suffering any loss to its power ratings. Likewise, a team that
 is an underdog by more than ten goals will not improve its rating when an
 opponent achieves the 10 goal,limit.
 
 Here is how it works
 
 If Team A is predicted to win by 15 goals, it need only win by 10 goals and no
 loss or gain is achieved by either opponent. Any loss in power points by the
 victor in 'under performing' will be made up by compensating that team in the TGI
 adjustment as shown on the Computer Ratings page. Likewise, any gain in
 rating points made by the loser who played "above it's expectation" (lost by
 10 instead of 15 goals) will lose power rating points compensating for the
 gain in the TGI adjustment as shown on the Computer Rating page.

 If Team A wins by more than ten goals, e.g., 12, 15, 25 goals, the team will
 not realize any benefit to it's power rating.

 The actual adjustment is determined by the "error" shown on each team's
 analysis page where the error is indicative of the so-called above (+) or
 below (-) performance for that game.

 The net effect of a "mismatch" game where a team is favored by more than
 ten goals and wins by atleast ten goals is to not count the game at all in
 developing a rating for either team as these mis-matches do not provide
 useful information to the formula in any case.

 If on the otherhand, an underdog by more than ten goals holds the favorite
 to less than ten goals, than, the favorite will lose rating points and the
 underdog will gain rating points. So in effect, the favorite has everything
 to lose but nothing to gain, and the underdog has everything to gain and
 nothing to lose when there is a predicted goal margin in excess of 10.

 So let's go through a few examples:

 Team A is favored by 20 goals over Team B

 (a) Team A wins by 10 goals
 (b) Team A wins by 24 goals
 (c) Team A wins by  4 goals

 For case (a) and (b), the game will have no effect on either team's rating.
 For case (c), Team A will lose rating points and Team B will gain rating
 points.

  Team A is favored by 6 goals over Team B

 (a) Team A wins by 10 goals
 (b) Team A wins by 24 goals
 (c) Team A wins by  4 goals
 (d) Team A wins by  8 goals
 (e) Team A loses by 3 goals

 For case (a) and (b), team A will beat its expected performance by up to
 but no more than 4 goals. Both cases (a) and (b) produce the same result on
 the power ratings. For case (c), (d) and (e), the ten goal rule
 does not apply.

  Team A is favored by 2 goals over Team B

 (a) Team A wins by 10 goals
 (b) Team A wins by 24 goals
 (c) Team A wins by  4 goals
 (d) Team A wins by  8 goals
 (e) Team A loses by 3 goals

 For case (a), Team A will gain significant points and Team B will lose
 an equal amount. For case (b), Team A will gain the same amount as in (a).
 limit and team B will lose an equal amount. For case (c), (d) and (e),
 the ten goal rule does not apply

 If a team is favored to win the game but loses by more then ten goals, then the
 team will suffer significantly but limited to a ten goal loss.

  In summary, there is no power rating gain by winning by more than 10 goals.
