But e.g. for defense contract stuff, I've accepted 1/4th my normal pay rate to be available for a span of hours (and then 150%, 2 hour minimum to actually do anything).
Yes, I can't drink, or become unreachable, and need to be able to get to a computer within a few minutes. But I can read a book, watch TV, work on hobby projects, etc.
Said differently, if the employer is going to pay you overtime rates for the period, why wouldn't they just have you actually work overtime, prioritizing a production outage over regular development, but regular development over watching TV?

150% for the entire time seems unreasonable.
