Going by the post and calculation below at Reddit. Serbian media (Blic) has a similar article as far as I can tell. https://www.reddit.com/r/tennis/comments/pxzqwv
Medvedev World No 1 Chance
If djokovic decides not to play till the 1st of November(or not win 77 points between now and november 1st) and Medvedev wins indian wells(these being the requirements). He will climb into the no 1 spot on the 1st of november with a 77 point lead(i.e if he does not play anything else except IW). And will drop back down to no 2 the following week regardless of his result at paris.
