What happens if a StarBondĀ® adjusts for more than one film on the same day?
The StarBond adjusts only once, simultaneously for multiple films. For each new film added to the TAG, the oldest film is dropped to maintain a maximum of five films.
What happens if two films in the TAG have the same release date?
The film with the smaller gross is dropped from the TAG first.
And in this case since NOTZP released first it would be the one to be dropped first from the TAG eventually.
