From MoodleDocs
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.

I second Mark, the details of the Scales and the aggregation methods can be very confusing. Could someone with more knowledge and understanding of this try to write a paragraph or two about these aggregation methods and why the other starts from zero and the other from one. I've had a lot of colleagues that have a hard time getting Scales to work with the "Grade to pass" + completion progress. Mostly this is because "fail,pass" computes as "1,2", though it is quite natural to assume "0,1". The page at also has no explanation of this "normalized" and "sum" aggregation methods.
