Rocky;
Yes it has. They have realized that most reserves fall in to the bottom 50 or 60% of a category, and therefore they can unstack as needed. I have seen in myself a few times over the last couple of months. I request certain days get unstacked, and then when I look at reserve coverage for that day, I can swap right in to it. Of course that is until they stick the PCS multiplier at 1.5!
Also the reserves required that you are seeing change, changes for a few reasons. One is someone swaps with the pot, does an APD, or goes on LTS, disability, sick leave etc. It can also go down when someone that is predicted to be though training and singed off is delayed.
Ina nut shell there are many reasons for it. This month especially, there are a lot of guys that are getting a paid month off because they did not train before the end of the conversion window, which further complicates things for those trying to get days off. Busy month all around.
