If the event was rescheduled outside of four weeks of the normal tournament date – Roland Garros, Rome, Istanbul and Strasbourg – the following applies:

2019 points will drop off after 104 weeks
2020 points will stay on for 52 weeks if the points earned are better than the 2021 results or the player does not compete at the event in 2021
In the event that 2020 points are used, they will drop off after 52 weeks, being replaced by the 2021 points
