Note that Q5 part 5 is slightly ambiguous. If a trip starts and stops on a line, it should only count as 1 trip (I accepted the answer 6677 prior to this clarification, but it is not correct).

Q4 part 2 - count drawn rounds as a +1 for all people who draw (and win). (so 45 is not the correct answer)
