The Cool Scale - Not cool, Not very cool, Fairly cool, Cool, Very cool, The coolest thing ever!
(Valued as 0/5pts, 1/5pt, 2/5pts, 3/5pts, 4/5pts, and 5/5pts respectively in any normalized aggregation method)
(Valued as 1, 2, 3, 4, 5, and 6 respectively in the sum aggregation method)

Please explain what the dickens "normalized" and "sum" aggregation method means. Is 'Natural' grading "normalised" or "sum" ? Who knows? Either way, scales don't seem to work with Natural grading and so the many teachers who want to use scales are excluded from using this intuitive method.

I have just realised that this is the v2.9 doc page -- my comments apply to v2.8 , so it might be different in v2.9. Even so, it would be good to explain the difference between 'normalised' and 'sum' and explain where 'natural' fits in.
