Obviously there are variables, but the rule-of-thumb I use for trading speed
for altitude is 1 knot = 9 feet. One should try this at altitude first, of
course.

As Justin said, 85 knots wouldn't buy you much assuming you stop the climb
at 50 - - and I prefer 60.

As a pilot who practices high speed low finishes, I
think that attention needs to be drawn to the fact
that 85knots is simply not fast enough when finishing
at 50 ft. At that speed, the height gained from a pull
is not going to be enough to complete a safe circuit.

I would agree that this low energy low finish was
possibly as a result of dehydration.
