bbell et al,
I was in the situation of not knowing if I would be in Jan, March(never got scheduled), May or August BMOQ. I maintained a close watch on the boards and posted a few questions and some info just like you. By checking with FM every couple or four weeks, and using what was posted, I was able to determine the likely probabilities involved.
It sounds like you are not likely going to be on May BMOQ. However, you might be (say 20%). Check with your FM regularly.
The long and the short of it, I was prepared for whichever start date was offered. I made a plan for for each contingency. The best piece of advice I can offer, look to the positive aspect of each possible start date. That way, whenever you do start, you can go off thinking (as I do) that things have worked out pretty darn good. I won't list the reasons, but May worked out almost perfectly. If you look for the positive aspects, you will find that your start date (whenever it is) will be ideal as well.
Cheers, and don't worry. When the call comes, your first thought will be, oh boy this is happening so darn fast!
Well, I have to go for a run now,
KMJAB
