Thanks, I appreciate the feedback and the link. Our main point of disagreement is the departure for the second leg. The normally scheduled flight time is reasonable and is completed in under 8 hours regularly. One argument is that since departing on the second leg is under your control, you are knowingly and willingly busting 8 hours. The other argument is that the whole day of flying is scheduled under 8 hours block time and the adverse weather conditions are beyond your control at the start of the day, therefore, 135.263 (d) states your are legal to finish the day/assigned flights.
