Proposed Victorian Round Robin Scoring System

Hi All,

After last comp several people mentioned that the scoring system we used ( a varient of the system used at Ideas Festival) could do with some tweeking.

It was felt that perhaps the system unfairly disadvantaged both people who had a bye and non spinners or non high KE weapons.

After looking at the points for last round I propose the following:

**Knockout 18 points
**Bye 9 points
**Judged match 5 points per judge (3 judges) spread between both bots, more points to the winner.

The knockout points is the most possible points awarded by the judges plus a 3 point bonus.

The bye (9 points) is an average number for a winning bot based on last comp. (3 points per judge)

If there are bots in the top of the points with the same score a single eliminator would be run to decide the winner. EG 2 bots fight off or 4 bots fight off. If 3 bots have same score top 4 bots would fight off. No 3 or 4 way fights.

What do people think? is it fair? can anyone see any problems. Looking at the data from the last event it would change 3rd place and below slightly, but would only create 2 instances of bots having the same score after 4 rounds.

sounds like some good improvments.
the old points system worked well at local events with just pushing but the time based bonus dont work as well with ke spinners as shown

when we looked at it the only fair thing for byes and forefits is to use averages.
If you average peoples scores then a bye can actually not count at all and a forfeit can still hurt.

regarding the KE spinner issue, thats why we split the comp into outright wins and points.

A spinner can get through by making spectacular shows (even if it looses) and an ultra reliable wedge will get through by winning its matches.

Basically the formula is this.

before the round people say if they are in or out. If they are out they "skip" the round, that counts against their average as half a fight.
If they are in they go into the draw.
If they get a bye that round isn't counted against their score at all, its like it never happened, so they aren't enhanced or penalised for it.
They have the fight and the judges pick winners and score the bots as well.
Somebody could have an awesome match with lots of control etc but still loose. (think Jolt Vs Robort)

When it comes time to draw the finals we use the following maths
average the score of a bot not counting any rounds where it got a bye giving average score.
average the wins of a bot not counting any rounds where it got a bye giving win ratio.

The robot with the highest win ratio (ie if they won all 4 fights and got a bye, they would have a win ratio of 1, if they lost 1 of 4 and had a bye their ratio would be .75) is pitted against the bot with the 2nd highest score, 2nd highest win ratio Vs highest score. (its seeded a little like tennis)

I know it sounds complicated but really all your doing different is keeping track of the number of rounds a bot competed with and doing some division.

We are working on a new version of the battleputer software that will integrate with a web site so you can have your day of battling, upload a file to the website and have a full historical database with rankings, photos, videos etc, If your interested in using it let me know.
