import numeric grades to letter grade site has conversion problems

Description
when importing items (clicker, scantron, spreadsheet items) to a letter grade site, if their scores are numeric and the scale is NOT 0-100 points, the resultant grades are a disaster. 0 is imported as 0 to a letter grade site, which is ok. eg:
for a scantron w/scale 0-100, the numeric scores are converted to the letter grade scale correctly.
for a clicker sheet, with scores 0-5, even if the point value is changed to 5 (from default 100) at import, all scores convert to F.
export a spreadsheet, add a new item w/100 point value, enter letter and number grades (for the heck of it) and imported grades will be correct. numeric grades are converted to letter grades.
as above but with a new item with point value over or under the 100 point scale, enter letters or numbers. the letter grades will be correct but the converted number grades won't.
as/David, he thinks this is the same issue that % gradebooks have. the import feature has been disabled for % sites.
something needs to be done for letter grade sites, so the IOR is aware of the 100 point scale limitation... prohibit import of numeric grades, do a mathematical conversion behind the scenes (student's score/item point value = % grade score, convert % grade to letter grade...
Per Constance's observation, this was addressed in 1.8.0 then.

Resolving.
Reviewed functions above and the application behaves as described as of v1.8.0.

We definitely don't do what we do with % gradebooks, and can improve this.

This is a know issue. If you import numeric values into a letter grade gradebook, it assumes that the numeric values are percentages. So anything that's not on a 100 points scale is not supported at this time.
