It's hard to get through this with informal reasoning but by varying what the different parts of the population looks like at different enrollment times (more like D9901, D9901+02a or D9902a, etc.), simulation shows that the power for the final look is somewhere in the mid to upper 80% assuming alpha .04. But, FWIW, if you trust the Halabi data that about 80% of the population look like D9901, then the power is above 90%. This is all log-rank.
