Thank you to *Bré471 and Doctor Blind for the informative replies.

Go easy on me as I'm a first time poster. Why is this the first week that Happy's weeks on charts corresponds with the OCC version of 15 weeks? Earlier posts on this forum have been a week behind (w/e 1/3 showed 13, for example). The OCC version showed a "debut" at 71 w/e 7/12 but was already showing "2 weeks" so I assume its proper debut was below 100 w/e 30/11. Any thoughts?
