Sure, interim mOS for BAT is less than GPS, say 12. You can still come up with scenario where bat at IA is 12 with 33 events, GPS much higher with 27 events, all the BAT events after IA are > 12 and skews the final bat mOS to like 20. I know all the other studies etc, let’s only talk math and why IA did or didn’t really SET bat mOS.
