I've had a read through all the previous comments regarding a grading system, and (mostly) gone with Senator8's proposal in the attached document. I know it won't suit everyone (it's not how I personally envisaged a new system working either) but on significant reflection it seems to be the best compromise between managing disparate and self-motivated interests and ensuring outright objectivity, whilst actually being able to be managed by simpletons. Constructive comments welcome, but let's also not go over old ground with personal axes. We clearly can't please everybody!
