no flipper, please you are the one adamant not to believe in Soft Lock, I beg your pardon. The Query discussion only erupt when you come to the data lock stages. There are two stages of data lock, one is soft and the final is hard. Query word is used only during this time. I agree with you SAP might be the showstopper now. And data scrubbing might well be done over. But the most time consuming process in the unblinding is Queries and Scrubbing and this take long very long in my mind. SAP is a document here with your non proportional hazard accounted for; OS will decide the outcome anyway. Sorry, had I been persistent.
