Great, but that only has to with when you rented.

Mine just posted too (on Oct 10, it says), but it took almost a whole month.

In other words, Avis->Carlson seems to happen about once a month at most.

It thus dpends when in the month your rental closes as to "how fast" it posts. My rental was Sep 5-15. Your presumably ended a week or two later, but since they all posted in the second week of October, yours seemed like "two weeks" while mine seemed like "almost a month".

Transfers between two partners don't take a set amount of time; they happen on a set frequency.
