5 weeks plus 7 weeks, 12 weeks for two releases, 6 weeks per release. It may be that they had to bring forward the Daytona 500 Update to coincide with the real-life event (it would have been over before the update was release, otherwise) and because the Ford Update was very light. Just a theory, though, you may be correct too.
