I suggest the following links about temperature. Personnally I aim at a germination of most seeds in 3 - 4 days, which means the highest recommended temperature. I sometimes cool down a bit at night.

I've seen this chart before. It has some merit, but it is missing the test method, growing media type and moisture content, number of samples per test and the number of times the testing was repeated under the same conditions.
It does point out that room temperature is more than fine for most seed types including tomatoes and peppers, but I would like to see more information regarding the test data.
If one is starting in a soil media, it would also be interesting to see a chart showing temperature/humidity vs. mold growth rates as well. After about 2 weeks at ~85F, I do recall seeing some mold development in a humid dome environment. How does mold affect germination, I don't know, but it seemed less likely for germination once mold set in.
