The 1994 BAOC Rankings are a mathematical concoction based on the event results. More details on these rankings and the mathematics behind them can be found in the following issues of the BAOC Bulletin: Jan/Feb 1993, Jan/Feb 1994, and Jul/Aug 1994.
Advanced CoursesThese rankings were done entirely by computer using an iteration rankings method. The major differences from the USOF ranking method are that everyone's result is used to determine the course difficulty, not just the top three, and that the ranking calculations are based on this year's results only (not on last year's rankings) via the use of iteration.
The Rossmoor Bar Green and Red courses were not included because of a missing control.
In the first half of the process, course difficulties are determined. Speed points on a course are supposed to be proportional to the orienteering speed of a competitor. Thus, if someone finishes a course in half the time of someone else, they will get twice as many points. That's the easy part.
The tricky part is figuring out how different courses compare, so that people who don't run directly against each other can be ranked side by side. One way to do this is to give each course a difficulty level or "gnarliness value" (GV). This way, the harder a course is, the more points you get for finishing it in a certain time.
It's very difficult (if not impossible) to determine the difficulty (or GV) of a course just by looking at how long or steep it is, so instead we use an estimate based on how all the competitors did. We don't directly ask each competitor how hard they thought the course was, because that would be subjective. What we do is compare how long they took with how fast they usually are to determine how hard they "experienced" the course to be.
The exact rules are even less readable than the above:
If you study that list of rules, you might notice that this ranking system is circular. The competitors' speeds are based on the GVs, which are based on the PGVs, which are based on the competitors' speeds. Most systems get around this difficulty by determining the course gnarliness values (GVs) using the previous year's rankings as the competitors' speeds for the initial step.
The Iteration rankings are not based on previous years' rankings, which means that the 1994 rankings are based only on the 1994 finishes. This makes the process circular, which requires you to start with some speeds, then calculate all the way through and get new speeds, and do this again and again until the numbers stop changing.
Once the numbers settle, you have a GV for each course. Then, for each competitor, you add back in their DNFs and DQs, giving them a very slow penalty time for the course, then calculate all of their scores, and average the top 75 percent of these to come up with the ranking points for the competitor.
We had 194 different advanced-course competitors this year, without having an A-meet to attract out-of-town orienteers (that's up from 117 last year). Of these, 81 raced 3 or more times. We're definitely doing something right!
