How can you quantify something like this? Software engineering has so many different specializations that it's possible that everyone is better in different ways. I might not be the best at solving problems such as the ones on TopCoder, or probably not the best at working with hardware, but if you ask me something specific about bioinformatics, I know that domain fairly well. I think it's strange to say you're better than 75% - 100% of all coders when you can't possibly have the knowledge about every field and every domain. All things considered, I'm definitely in the 0 - 25%.
