The step weighting process is determined by Number of Entries per Tag
If you only have 3 entries, and they each have different Tags, they’re all going to be weighted the same. It only builds the weighting by ratio to others, so for example, even if you have 12 entries, and 4 were assigned tag1, 4 were assigned tag2, and 4 were assigned tag3, they all hold the same ratio, and will output the same Step.
The number of times the top tag is used establishes the top of the scale with 0 as the bottom. You specify the number of groups into which your tags will be sorted. Each of your top tags will be evaluated as to which group they belong in. They will be given a numerical ranking based on this.
For example, imagine you have 3 tags on your site; apple, orange and microsoft. You specify that you want to show a cloud with 3 groups. If apple is used 12 times, orange 7 and microsoft 1, the top of your scale will be 12. Apple will get the highest rank and the largest font. Microsoft will get the smallest ranking and font. Orange will get the middle font because it falls into the middle grouping. The range for falling into the lowest group would be 0-4. For the middle, 5-8. And for the top, 9-12.
