bale accumulator questions

I have baled hay sm squares and 4x5 rounds for many years. I am trying a Khun's 1036F 10 bale flat accumulator for the first time this year. We have a NH 5070 hayliner, we ted with a 6 basket, we have two rotary rakes one 9' one 11' and cut with a 10' diskbine,We have 1 24', 4 20' and 3 22' racks. Most of our fields are small odd shaped with some small hills. What is the best way to rake double 9' or single 11' windrow? How fast can you load 120 to 150 bales on a rack after you get good at it? About how many bales per hour can I expect to bale with this system after it is working properly? Plan on baling with a JD 6420 with the power quad or would a JD 7400 with the power quad be better? Sorry for so many questions thanks in advance
