Bruce's numbers are a pretty accurate rule of thumb. In an earlier
thread there was some doubt expressed as to whether these
'theoretical' numbers can be achieved in flight. I took a look at
some flight logs and found most of the time you convert into height
~90% of your kinetic energy (+/- the accuracy of my logger). There
was one pull up where I only got 75% and one case where I got 100%
(!). Best not to count on getting every last inch.

Agreed, and thanks for the confirmation.

Could headwind account for the 100% example? And tailwind for the 75%?
In other words, your airspeed was not the same as your ground speed?
