Ok, so I just have a few questions regarding the Paragon Bluebird kiln schedule that I'm going to use. Many thanks to Paul Ewing for the schedule.
On the Hold 3 & Hold 4 cycles: why hold for only 1 minute? What's the benefit and why should I do it?
At the end where he discusses "skipping out" of the Hold 1 cycle to go to the annealing cycle: how do I do that? In the past, every time I try to push the cycle ahead I end up dumping myself out of the menu and back to start.

Hld1(Hold 1) = 4.00 ( 4 hours hold time ) the amount of time you have to work
Ra 2(Ramp 2) = 1400 ( it will only take a few minutes to go from 950 to 968 )
oF 2(Temperature 2) = 968 ( annealing temp )
Hld2(Hold 2) = 1.00 ( hold for 1 hour, the ANNEAL SOAK time ) Sufficient for a 1” bead
Ra 3 (Ramp 3) = 120 ( equates to 2 degrees per minute, the ANNEAL RAMP )
oF 3(Temperature 3) = 848 ( well below the 860 'strain point' to be safe )
Hld3(Hold 3) = .01 ( hold for 1 minute )
Ra 4 (Ramp 4) = 200 (controlled cool off, some people don’t use this step)
oF 4(Temperature 4)= 400(the temperature a which your kiln will shut off and cool on its own)
Hld4(Hold 4)= .01 (hold for 1 minute)
With Hld1 = 4.00, the kiln will hold at the 950 "garaging" temp for 4 hours. If you make beads for a longer time you can increase the number. Don’t shorten it though because you can “skip” out and go to the annealing step when you are finished working.
