Well, looks like 47 of us voted on the Bomb Drop poll and the majority of us are between the one year and two year mark.
Considering there are around 540 registered users, 1/2 of them have at least 1 post, I am not sure that 47 responses is so great yet.
Also considering that this website will be 1 year old in May, the statistics seem to follow the group of us that have been on the website.
My first bomb drop will be over two years in May, my second one was only 3 months ago.
So my point is that Bomb Drop is not always at a consistant time within the crisis and can happen in replay or any time after up until the breaking of withdrawal.
