I am not sure if it is correct technique, but I have learned over many =
years that a slip followed by a skid seems to increase climb rate. The =
idea is to alternate between the two maneuvers quickly. If done =
properly and at a rapid rate, the result is amazing.

Are you doing this with stick or with rudder? Sounds
like sculling to me.

Bob,

Normally I trust what you post, but I had to check to make sure today
isn't April 1.

Bob,

That only works if your ship has a laminar airfoil. I guess that eliminates
anything you fly ;-)

Bob,

I fly that uncoordinated, but somehow I still gain altitude, too...

On a bad day the string just refuses to lie still. On a good one it hardly ever
moves - and the vario makes happy noises.
Maybe it is a Schempp-Hirth thing, but my old Cirrus also climbs best with a
little bit of string deflection. The geometry would have a tiny two or three
degrees slip indicated if you fly perfectly co-ordinated, and it is best with
quite a lot more than that.

Could it be a erroneous information from the instruments?
They are only accurate if you fly straight. As soon as you go sideways,
the airspeed indicator, and the VSI, will not longer be "true", since
you are adding quite a bit of airflow over the statics vents.
To get a static pressure, you must fly straight.
"Playing" with your rudders to get a better climb is quite simply....a
myth!
(And I must add that it is an urban legend that I have been hearing for
the last 25 years!)
