The last movie he adjusted for when MacGruber was added and Kiss Kiss, Bang Bang was dropped. He will next adjust when Kill the Irishman has been out and racking up box office for 12 weeks (because it's limited release). Then several weeks after that he will adjust for Bloodworth. Wide release movies it happens after 3 weeks. There are many nuances such as limited movies that go wide and limited movies that don't report box office and so on... but ~90% of movies follow the same rules. The adjusts happen on Tuesdays and the stocks will halt the day before they adjust.
Keep in mind that if the most recent adjust had only made 20 million at the time the starbond adjusted but went on to make 35 million... then that extra 15 million gets added in to the calculation the next time the starbond adjusts.
To estimate an adjust about to happen... multiply the TAG by 5, subtract the movie about to be dropped, add the amount of the movie being added, and add the amount the most recent adjust made above its delist price. Then divide by 5 and you have your adjust price.
Got it?
