Well just personally i dont think the off season weeks should count because the whole prestige in being number 1 is that every week your competitors have the opportunity to take the no 1 ranking off of you and the reason you keep it is because you are the better than them. But in the off season, their is no opportunity for them to take it off you, so you aren't really proving anything then
. Do you get what I mean?
I dont know why they count it in the ATP rankings, I thinks its stupid
