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 https://docs.moodle.org/36/en/Grade_aggregation also has no explanation of this "normalized" and "sum" aggregation methods.

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.
