Brooder plates (and the MHP) don't work like a heat lamp so forget about the 95 degrees and 5 degrees less each week. Set the front of the heat plate so it's even with the chicks back and the back of the heat plate so it's a few notches lower. This will make the plate angled. The chicks will find their comfort zone under the plate. You will have to make height adjustments as the chicks grow.
There are lots of threads here on BYC about using brooder plates. Look around a little bit and I'm sure your fears will be calmed. They really are 100% better than heat lamps.
