Grand Prix Tables and Methodology 2016-17

We give here the tables and formulas used to calculate the Grand Prix points awarded for each tournament played in.

The table below is a sample (not the current) standard Grand Prix points table. To find your Grand Prix point score in the table below, find the row for your section and the column for your score in that section.

For example, let’s say you scored 3 wins in a 4-round Reserve section. You would then get 315 points added to your Grand Prix total points score.

Note that, for non-negative scores, it takes 1½ extra points to double your score. For example, a score of 2 in the Primary section is worth 99 points, while a score of 3.5 is worth 198 points.

Additional notes:

-         A score of just ½ point in a 4-round event does not earn Grand Prix points.

-         There are small differences caused by rounding the results of calculations (explained under Formulas below). We always use the rounded scores, as stated in the table, to compute total Grand Prix points.

We adjust this table by shifting the negative scores one column to the left, and dropping the ½ point scores in the 4-round sections.

As noted earlier, for non-negative scores, it takes 1½ extra points to double your score. Negative scores are adjusted one column (½ point) to the left, so that they earn fewer relative points. A side effect is that within the negative score columns it takes only one extra point to double your score.

As also mentioned, note that a score of just ½ point in a 4-round event does not earn Grand Prix points.

Feb 2013 Table for 3-round sections. Since the Future Masters is actually run as a 3-rounder, we use the table for a 3-round tournament. This is done by shifting all cells ½ point  to the right. Thus, the score for 3.5 points in the 4-round table becomes the score for 3 points in the 3-point table. The rationale: since you will be playing an opponent who has matched your score through 3 rounds, the likely average outcome of the 4th game is ½  point.

Grand Prix tables for other numbers of rounds, if and when needed, will be formulated using the same approach.

Combined table. We combine the first row of the 3-round table with the remaining rows of the 4-round table to produce the current standard table:
