JustRanks Score
How far the product moved over the selected period, 0–100. Above 50 means it climbed, below 50 means it slipped.
A momentum score, not a ranking. It compares where the product stood at the start of the period you selected with where it stands at the end: 50 means it held steady, above 50 means it climbed, below 50 means it slipped, and the further from 50, the larger the move. Because it measures the period you actually chose, a 90-day score describes 90 days of movement — not an average of shorter stretches. Switching the date range therefore changes what the number is about, which is the point of it. The comparison figure next to it is the same measure for the preceding period of equal length. A score of 65 against a previous 70 means the product is still climbing, just less steeply than before.
