I have 5 High Arcana feats: Spellpower 1 & 2, SLA 5th, 6th and 9th. That should be (in order) 5th, 7th, 5th, 6th & 9th.
The spell slots taken seem to be random to me, but perhaps you can make more sense of it. Here's a screenshot with my preparations and logs of what was taken. I prepared the 1st spell that I can cast in alphabetical order. I have also tried to test my CL, which should be 32, by casting Non Detection, which gives the effect of DC 15+CL. Seems like I reap benefits without sacrifice.
