How do you guys define good vs. bad trips? Is it the ratio of TAFB divided by credit hours? So for example, a trip with a TAFB of 80 hours with a credit of 16 hours would be bad, whereas a trip with a TAFB of 80 hours with a credit of 30 hours would be good? Or am I dramatically oversimplifying?

I guess there are other factors that go into it...like in December, I'd probably take a lower-credit trip to San Diego as opposed to a higher-credit trip to Calgary...

Anyhow, would just be curious to learn about how you judge the 'quality' of a trip beyond the very simple metric of TAFB/Credit hours.
