I've decided to collect my own data. I'm recording the air temperature inside of the toaster to make sure that I start each trial at 80 degrees Fahrenheit. I'm also setting the toaster randomly. I have a super-geeky way to do make the random selections, as you can see below.
This is a slow process, as it takes 10 to 15 minutes for the toaster to cool. Hopefully I can finish collecting my data before the sacrificial loaf goes stale. I'll have to write another NSF grant if it does.
