I started about the beginning of January last year on the Excel/ XLS. I did the reserve schedule until August. With the holdiday, extended day, and OT I came out with 50k, not including perdiem or 401k match. I extended 6 times and worked 5 holidays. Differences pay is $225 a month for XLS/ Excel and OT adds up fast on the Excel. I could have had 7 & 7 3 months earlier if I wanted, but I was a money ***** until I went on 7 & 7.
