I've a question about weights in workshops.
Weights in the Accumulative, Error banded and Rubric avaluation strategies are 0, 0'25, 0'5, 0'75, 1, 1'5, 2, 4 and their negative values.
Why doesn't workshop let to choose values as 3 or -3? Are there any reason for that? Is it a statistical question?
Thank you for your help
