This is certainly my experience. I find that I can usually handle
higher winds by adding 1/2" to 1" of extra outhaul. Too much definately
causes the sail to be harder to handle.
I was reminded of this just a couple of weeks ago when my 5.4 was being
overpowered (back-hand pull) in my usual setting, and found that 3/4" of
extra outhaul (one boom notch) made the sail very hard to keep in trim.
3/8" extra was much easier to handle than the other two cases.
I tend to downhaul maybe 1/4" extra when I am woriied about being
overpowered, but I have not changed my downhaul in the middle of a
session lately.
