DQ4 is absolutely correct. The problem is not many pilots are aware of a racetrack entry and when one is performed it takes F/O's by surprise.
You could argue that the entry should be briefed but shouldn't "standard racetrack entry" be sufficient??
As for the speed. If I caught any Pilot flying in excess of the published speed on a published procedure he wouldn't be doing it again. He would be taken off line. It is dangerous and neglegent. Standard speeds are essential for terrain clearence and it is unsatisfactory for a pilot to fly any faster than that published just because he thinks it's ok. Its the same guy that throws away the plate and we read about him in chirp in the CFIT section.
If any of you fly in a non standard manner, ask yourself if you should be flying at all. I wouldn't want my children in the cabin with aircraft flying procedures at 280 knots. No way.
