If the majority of participants do, like you, decide to stay away from the 5 day window. You are better off actually allocating in the said window. If "timing" is of concern, you should just dollar cost average in. So say you want to allocate 100 eth to eos. Then allocate 22.22 (200,000,000/900,000,000)*100 in first window and then .22 eth every day for then next 350 days.
