What makes it useful is that it prepares you for the eventual dead-stick, and it will happen, no doubt, if you stay in this hobby long enough. When it happens, well, you won't be all that surprised and will know what to do right away. Just remember that dead-sticks occur in the most inadvantageous times... like Murphy's law, ya know?
And, I'll tell you, even now, I do several touch-and-go's and full stop landings on the first tank of fuel of the day. Just to keep in practice and to keep sharp.
Later, and again, nice job with that plane.
