a. I like this change
b. I'd love to see some test coverage of set_temp_fail_intervals
c. after giving others time to look it over, I'll merge it even without b.

I'm not opposed to testing, but not sure how it works here. I'll have to learn the details first. Is there any helpful information on getting started with that? Also, I wrote the parsing code to fail over back to the original 2^N method at any sign of trouble...although I'm not saying someone couldn't input something that would totally break it. I might need to add a limit on the array size to keep someone from consuming too much memory with a ridiculous multiplier.

Is there any helpful information on getting started with that?

Looking at the existing tests is the best documentation we have.

That's something test coverage could help answer.

I added some tests. Please let me know if that meets your expectations.
