MTPoints: point scoring for multi
day events |
Multi day O events are going to calculate the overall results
by point score methods which enable runners to eliminate their worst results.
Thus runners need not to take part in all stages which allows them to use
this additional free time for other recreational activities.
Initially, this requirement
had been demanded by the multi day events in France, Scotland
and Hungary. My solution is the application MTPoints.
This is an add on for MT2003.
Currently MTPoints supports four scoring
methods.
Using the Standard method, a runner's points are given by
1000 - 200*(Mean time - runner's time)/standard
deviation.
Mean time and standard deviation are calculated from all running times
of the category. This formula is the mathematical standard for normalizing
data. It is often used in sports to allow to add results which have to
be measured by different units. In orienteering, a similar formula is
used for the world rankings. Multi day events with a chase start should
use this formula.
Using the Scottish method, a runner's points are given
by
1000*winner's time/runner's time.
This formula had been used at the Scottish 6days in former times. Of
course it will determine the correct winner. However, the point score
of the remaining runners depends extremely on the winning time and the
terrain specific time differences. Thus the calculation of chase start
times may be not objective enough.
Using the Per cent method, a runner's
points are given by
Maximum points - (runner's time-winner's
time)/winner's time*100.
In other words, the point score is the maximum value minus the time difference
as a percentage. A maximum value of 100 means that all runners who are
more than 100% behind the leader (the doubled winning time), will get
zero points.
This method is being used for many national and regional ranking systems.
It is also suitable if you are performing a chase start.
Using the Danish
method, a runner's points are given by
Maximum points - difference to the winner
in full minutes.
Only full minutes count for the difference. That means that all runners
within the same difference minute will get the same points. Especially,
all runners witin less than one minute will get the maximum points like
the winner.
This method comes from Denmark.
You can define the precision by the number
of decimal places and how they should be calculated (rounded or truncated).
You
can report the point score results based on the MT2003 results. You can
define how many results until the current stage should be taken
to calculate the overall point score. MTPoints offers the well known
preliminary results, with an additional column for the current point
scores.
To calculate the chase start times, the overall points have to be converted
back to times.
MTPoints is available for MT2003 V.10.2. Registered users
of MT2003 can download MTPoints
and use it for free.
