If you want in game logic, sewing kit has multiple uses, and each use repairs 62.5%. So there is nothing weird there.

If you are looking for game mechanics, as explained in sewing kit page, each use restores 5 days of use, regardless of what item it is used on (but won't exceed max). So longer the item lasts, lower the percentage repaired.
