We need to hear data is being collected and mark that date. How long it takes to analyze interim data. IMO, it's completely acceptable to hit the conference on the 8th without the interim data, but we do need to hear we've reached that halfway point in Q3. I think we will. And it's possible we'll just see the data without hearing we're at the halfway point. Then maybe we can measure from there. 2nd half goes much smoother and faster imo. I don't thing completing in Q4 is unreasonable.
