My information was 220 MACE as of Jan 20 2019.  Of course it may mean that my data point was dated...but it would suggest 1 to 2 MACE events a week, based on Pomp's rumor. 

So somewhere between 15 and 30 weeks, starting from early Jan.  That would mean anywhere from April 16 to July 30 (Jan 1 starting point, with 15 to 30 weeks after that). 

I am coming around to middle of May as the most likely end of Phase 3 announcement.  Another 11 weeks to go before we hit May 15!  

Meanwhile, I think the share price will become ever more volatile as some holders get nervous.
