Yes you are right dear. However for my NOC i.e. 3112, I have observed that first sho78 received MR then me and then BDPA. We all received MR in March 2012. So I think, mostly, when they start working on an NOC, they keep on working. What do you think?
Dear OPTIMIST well come on this forum, updated with your name thanks
