You can easily calibrate your kiln.
Take one of those round oven thermometers.
Set your kiln to 400 degrees.
Put your oven thermometer inside.
Wait for the kiln to come up to temp.
Check the oven thermometer reading.
Do they match?
FWIW, I found my kiln was 40-45 degrees hotter than what the pyrometer said.
I made adjustments in my program.
I now anneal at 900. (Instead of 940.)
No more overstriking.
