You're talking about a 3 day with no block on day 2 (long layover?)

That's an interesting thought that I haven't ever considered. If it works, you might be able to save 1 PB day - I'm not sure how they'd work that scenario. I was more referring to a 3 day for 15:45 with low block. I've heard of guys dropping day 1 thinking they're going to get 5:15 but actually only get the hard time for that day since credit (DPA in this case) would pay on day 3.

I'd call Contract Admin on Monday morning to get a better answer. I'll see if I can find something in the meantime.
