I know that race rankings, i.e. points only from this calendar year, are used to decide players at year end ATP/WTA championships.
My question is whether the rankings just one week before the finals are taken into consideration, or whether the decision is made sooner.
For example, this year in WTA tour Kremlin Cup in Moscow and Luxembourg Open in Kockelscheuer will be played during the week before the WTA Finals. Can the points from these tournaments influence who will be contenders at the year end championships?
The situation in ATP Tour is a bit different (at least this year) since no tournaments are scheduled during the last week before the ATP World Tour Finals. Similarly, before WTA Elite Trophy there will be one week gap (since no players will play at both at WTA Finals and WTA Elite Trophy). But we can still ask the same question - which tournaments will be relevant for the decision who qualifies for these year-end tournaments.
