This page describes how race handicaps, points, and awards are calculated. The
information published here is a condensed version of the official rules that
govern FWRA events. This is not the official document that describes race
scoring. The official rules are published by the FWRA. You can read them here:
FWRA Rules 2003
Please review the new scoring system and the rules for 2004/4005 season.(doc file 58Kb)
This is how it works:
-
A score is calculated for each racer. The scoring method varies from
race to race. For two-run races, it can be the total time, the best of the two
times, or the second time only (practice run). For Sierra League, it is usually
the total time.
-
A zero time is calculated for each pacesetter using their score and their
pacesetter rating:
zTime = Score / ((1 + Rating)/100)
Theoretically, this is time that a world champion would get on this course.
Pacesetters were rated at the end of last season.
-
Pacesetter zTimes are chosen. Some zTimes are not used for calculating
hadicaps. If the pacesetter skiied far better or worse than their rating, their
zTime is usually ignored. On the results sheets, the pacesetters that are
turned on are marked with this symbol: > .
-
The zPar is calculated for each course. It is the average of all
zTimes that have not been turned off.
-
Sometimes the zPar is adjusted. This occurs when the number of strikes exceeds
the FWRA maximum. ZPar adjustments are somewhat artificial. Sierra League
prefers to turn pacesetter zTimes on or off before using an adjustment.
The zPar adjustment is displayed on the report at the top of each page as is
the adjusted zPar .
-
Each racer is assigned a handicap based on their score and the adjusted zPar:
Handicap = ( Score / zPar - 1 ) x 100
You can interpret Handicap as a percentage your time is slower than of a world champion.
For example if your time is 60 sec and your handicap is 20, the champion's time would have been 50 sec.
-
First-time racers are assigned to classes based on their handicap and on the
judgement of the race director.
-
Points and awards are assigned according to FWRA standards. The points and
awards depend on a racer's place within their class and on the number of
starters in that class. To qualify for points and awards, a racer must ski
better than the high handicap for their class or beat someone in their class.
See the FWRA rules for more information.
-
Any racers who ski better than the low handicap for their class will
be given a strike. If they ski better than the low handicap for the
next level up, they get two strikes. And so on... The score that corresponds to
the low handicap is displayed above each class as the break time .
-
Any racers who have two or more strikes will be promoted to the next level
before the next race. This is called a bump. For each bump, two
strikes are removed from the racer's record. Unused strikes remain valid for
two full seasons. Bumps are marked on the right side of the results with an
asterisk: * .
