It seems like many rubrics for scoring an idea's impact use scales not supported by Canny. For example, I want to mimic the RICE model and be able to score my impact using a common scale of .25, .5, 1, 2, and 3. Five stars is the closest supported measurement in Canny. However, that means that the greatest possible disparity in value is 5 rather than 12. I could use Fibonacci, but then there are too many options (I want a limited number of options).
