How does re-list affect the best match score of an item?
Relisting an item will carry over an item's best match score, in most cases. Changes that will badly impact the best match score are:
1. Category updates (changing, adding, or removing) for either the primary or secondary category will trigger a reset.
2. Item condition removal.
3. In addition, you should relist as soon as the original item ends. This has an impact on the recent sales calculation.
