Scheduling Question for the experts.

I bid reserve for October and my goal was to only make 1 commute to do it (long story....). I said I didn't want to fly on 30, 31, 1, 2, 3, 4, etc.. up to the 12th. So basically I'd be on reserve from 12-28 Oct. Just got my schedule and it's broken my reserve into 3 blocks (3-5 Oct and then two blocks starting on the 10th but ending early than I wanted).

I look at the people less senior to me and there plenty who have reserve on every one of the days I wanted to be on reserve. I thought when you put the days off you wanted in it went in the order you placed them, so worst case it should have put the the reserve days starting from the 12th and working backwards to the 1st.

Anybody know why it ended up this way? Reasons report just says "partially honored".
