| Band | Share of session | Bars | Separate visits | Median visit | Longest visit | |
|---|---|---|---|---|---|---|
| Above 80 | 42.6% | 29 | 3 | 105 min | 255 min | |
| Between 20 and 80 | 23.5% | 16 | 6 | 37 min | 75 min | |

The fast line is the unsmoothed version of the same range calculation, so it reaches the extremes far more often than the smoothed %K and leaves them sooner.
Here the reading entered overbought territory 3 times, with a median stay of 105 minutes and a longest of 255. The gap between this page's visit count and the smoothed Stochastics page for the same session is a direct measure of how much the smoothing removes.
