20%? That would make them 25:10 for a 21:00 trip today. I think the optimizer is more than capable of keeping credit about the same and barely moving the needle on trip QOL. The only trip construction improvements are for the outliers. Look at your trips and tell me how many have back to back <12 hr overnights? How many where the 2.5 hr min day would actually raise the credit of the trip? How many 4 hour sits do you have? I'm a NB pilot and none of those affect my trips. And if they do apply to you, I guarantee the trip credit won't improve by 20%.
