"must have failed" referred to P2b and NOT to B unsure why you bring it up. Other than I guess you meant to say you are basing your hopes on B- which makes sense.
P silence is actually a very good argument for failure- sorry. look at all the B OM hoopla. Plenty of B chatter, even unnecessary chatter
Esp those pathetic April PR's that are not statistically sound re B OM. Now those are reasons to worry about B OM- why issue those weak subgroup data points at all? Sad.
