I have never used that kiln, but I can tell you my kiln cycle
I hold my beads at 515C until I finish work, then when I put my last bead of the day in I keep it at 515C for an extra hour, after that my kiln ramps down to 220C at I think it's around 150C an hour. Once it reaches 220C the kiln turns off and it takes a while for it to reach room temperature.
I'm sure everyone uses different cycles out there, this one has always worked for me.
All the best !
