Default Firing schedule for batch annealing?

I got my very first kiln for Christmas and I'm in need of a firing schedule for my beads. Most of my glass is 104 COE and I'll be batch annealing. I've contacted my glass distributer several times but have yet to get a response; I'm hoping someone here can lend me some wisdom!
My kiln is a Paragon Fusion 7. Most of my beads are relatively small; I'd say less than an inch in diameter. Any advice you all are willing to share will be appreciated. Thank you!

You'll probably get a few different answers to this, but I just go to a 920 anneal (200 dph) because I use quite a bit of StrikingColor glass, hold for 1 hour 30 minutes, drop 100 dph to 700, off. I am primarily a glass fuser, so I use a lower and slower approach to my top temp and anneal longer than one would normally.

Ok! That's a great place to start; thank you very much. There's no harm in bringing the temp up slowly, right? I can err on the slow side?

Keeping your temperatures low enough to do the job, and increasing your hold time to accomplish that, has gained a lot of momentum in the fused glass field. Beads are no different in that you anneal for the thickness, not the overall size. You would anneal a 4" long focal the same as you would a 1" focal, as long as they are the same circumference. Spectrum glass has dropped their anneal by 10 degrees and Bullseye by 60 degrees in recent years.
