| // This means both the control and enabled groups will adjust the |

| // improvement will look inflated because the denominator (i.e., how long the |
| // navigation was to begin with) was incorrectly too small. We think this |
| // could be fine as long as we don't use FCP or similar metrics based on the |
| // common_params start time to judge the size of the improvement. |
