|This is a bit out of the box, but I was thinking that a "Net" winner, based upon a handicap, would be a nice addition to the challenge awards. This isn't meant to take away from the current blue/yellow/red winners, but to provide a way to recognize those working their way up the learning curve.
Here's the basics:
Similar to a golf handicap, take the last highest 15 scores of a photographer's last 30 entries and calcluate their average. You must have at least 30 entries to get a handicap assigned.
For any subsequent challenge, you net someone's score against their handicap to determine their net score. As an example, someone that scored a 5.75 in a challenge with a handicap of 5.5 would have a "net" scrore of +.25.
The person with the highest net score would win the "Net Improved" ribbon for that challenge.
To avoid impacting the prestige of the current ribbons, I would suggest posting the winners on a separate row, in a section devoted to the Net winners.
