Default How to get maximum height on a winch launch?

Ian,

winch launching my Calif over 8 years on a 280 hp winch was exactly "full
power until release", and that was the only way to go.
So, in some cases this type of instructions actually does work.

Full power for the whole launch works when the winch is severely
underpowered. As more powerful winches are introduced, you will find there
are points in the launch where the driver must reduce power to maintain
constant tension.

It's the inflexibility of "full power all the way" which worries me.
I've lobbed K21's off at Sutton Bank on windless days which needed full
throttle, windy days on which a whisker over idle was quite enough and
days when things changed from calm to windy half way up the launch. A
driver who thinks "K21 - right, full power" is ... I was going to right
"get himself into trouble oneday" but that isn't quite right. He's
going to get two other people into trouble one day.
