A big well done to Kradovech for suggesting adding User name to end of your predictions. As somebody who converted the pickems data into a spreadsheet over a season I can confirm it will make a huge difference in how easy it is to get data ready for calculating results. It will take less than a quarter of the time to get ready to calculate scores.
It will also improve accuracy with greatly reduced chance of an error like I made with Monte Carlo data (apologies Kaps).
The concern AnttiL raised about someone using another persons username is easily reviewed for. Have a look at Mexico pickems and you will see how easy it is to review that Username in pickem is the same as posters username.
Again well done Kradovech for figuring out a simple easy to do solution.
