Sywell Cambridge Leicester Sywell is never 150 miles is it?
Edit: Just checked on Skydemon, it's 107 miles. Bit odd.
Probably just felt longer - not sure where you got the 150 miles from, cant see it on this thread?? Also, he says
Remember taxiing out behind a C130 from Marshall's
so from that the Sywell - Cambridge leg is not part of the bit done flap down.
As far as continuing with a failure goes, my view is much the same as Genghis, though we are both pretty experienced and some failures a pilot with low hours might get worried over we might be just considering a minor annoyance.

I would also go with BFs suggestion of Vfe -10, at Vfe it only needs a lapse in concentration or an unexpected updraft and you are at Vfe +10.
Edited to say
Re the 150 mile , comment, I think it refers to the comment re a qualifying cross country which should be 150 nm and 2 intermediate landings
,
Of course, should have picked up on that
