It is worth the bother doing. I know it helped me with the CL stunters. And their performance is more easily tested than any other kind of model we fly.

But there's also a subtle thing about trying stuff.

If what you try seems to work for you, it has. If you try something and think it helped, it did. It doesn't matter if it really did or not. If we fly with more confidence, we almost always fly better. So indirectly, it did work.

(Unfortunately, if something doesn't seem to work for you, then it hasn't, even if you're wrong and it's really helping. So be slow to decide that your tests disprove anything.)
