The QLD Ninja Cup is a points based league where competitors can accumulate points by their success on the Ninja obstacle courses run throughout the year by rotating Ninja Gym venues. The events range in price from $25 to $80 to enter, each with their own prizes…all accumulating to the finals at the end of the year.

The Scoring System:
We’re using a 100 point system for each event.
We want to reward ninjas who placed high against more competition so they received more points than a ninja who placed high against less participants at an event.
Lets run a few scenarios to help explain:
John comes 1st of 10 participants
Chris comes 2nd of 10 participants
Mary comes 3rd of 10 participants
(and so on)
John’s score for Event A is calculated as follows:
First we calculate the “competition modifier” which is John’s position divided by the total number of participants
1/10 = 0.1 (or 10%)
Then we start with 100 points and deduct the “competition modifier” value
100 – (100 x 0.1) = 90 points
The total scores for Event A are:
John: 90 points
Chris: 80 points
Mary: 70 points
David comes 1st of 20 participants
Carol comes 2nd of 20 participants
Mark comes 3rd of 20 participants
(and so on)
David’s score for Event B is calculated as follows:
1/20 = 0.05 (or 5%)
100 – (100 x 0.05) = 95 points
The total scores for Event B are:
David: 95 points
Carol: 90 points
Mark: 85 points
So based on the fact that David has to be 20 participants instead of 10 participants, he actually is the current national leader.
Fast forward a few events and lets pretend that some of these ninjas have actually competed in quite a few events in hopes to improve their national ranking (or just because they love Ninja comps and want to do all of them).
David: 95 | 85 | 88 | 45 | avg: 78.25)
John: 90 (avg: 90)
Chris: 80 | 85 | 90 | 95 | 88 (avg: 87.6)
Carol: 90 | 75 (avg: 82.5)
(and so on)
David’s average for all 4 events is 78.25 but clearly he had a bad run and shouldn’t be penalised for a bad event when his other runs have been awesome.
Furthermore, John only got to one event, which he scored really well in, but by no means should John rate higher than David or Chris who have both had performances above and beyond his one event.
So the solution is to take the top 2 scores per ninja and find their average:
Chris: 92.5 (2 events)
David: 91.5 (2 events)
Carol: 82.5 (2 events)
John: 45 (only did 1 event but the average across 2 events is 45)
This starts to even things out a bit, with Chris taking the lead.
As a bonus, we also reward ninja’s for participation, so the Australian Ninja Games leaderboard includes a participation modifier.
If you participate in 1 event, you get a 1% bonus to your score.
If you participate in 2 events, you get a 2% bonus to your score.
If you participate in 3 or more events, you get a 3% bonus to your score.
i.e. David has done 4 events, so we apply a 3% “bonus”. Introducing this logic, we would see the scores changes as follows:
Chris: 95.275 (4 events earns a 3% bonus)
David: 94.245 (4 events earns a 3% bonus)
Carol: 84.15 (2 events earns a 2% bonus)
John: 45.45 (1 event earns a 1% bonus)
In the event of a draw for 1st place at the end of the season, we will use the next highest score from a 3rd and calculate the winner that way.
