Thinking about it, when I took the bike on a track day, when the profile more closely fits your useage, the engine gave up half way through... so not sure i'm on a winning argument here.
On the commander I fly, I've been taught to set the engine monitor (EDM700) to show shock cooling - it shouts if cooling exceeds 50F/min anyway, which makes life easier (albeit meant a descent at 160Knots - cruise is 130) to keep in enough engine power to avoid cooling too quickly.
Thanks,
Alex
