controller firing instructions

In looking to the archives for a glaze recipe, it listed the firing
instructions as such:

Firing ramp with an electric controller is:
100c p/h to 600c (212f - 1112f)
150c p/h to 1140c (302f - 2084f)
80c p/h to 1220c (176f - 2228f)
15 min. soak
cool down max. to 900c (1652f)
Hold 1 hour
Shut off kiln

Specifically, I don't understand the third ramp instructions because it
starts out less than the previous though extends beyond previous ramp specs.
I haven't fired in a while as I've been away from ceramics, so maybe I've
forgotten something.

Thanks for any feedback,
Centa
