I learned on a Nikon FE with a split focusing screen.
That's one focus point, focused manually.
I focus-recomposed pretty much daily.
Using lenses such as a 50 1.4, 300 4.5 for birds, etc. I never had a problem getting sharp shots.
For some reason I don't have any trouble getting precise focus after focus recomposing with any of my lenses. I seriously think that this whole "dont focus-recompose" thing is blown way out of proportion. I still don't have trouble getting sharp shots after focus recomposing, even wide open.
I know that there is a scientific basis to it. But it the effects of focus-recomposing should even be diminished the longer a lens gets because you have to move the lens LESS to get the desired framing (smaller angle of view)
If I want to focus recompose my 17-40 i have to swing the camera a lot of degrees. My 70-200 I hardly move the camera at all.
My shots are still sharp.
It depends on your method. Pretend if the camera was on a tripod, you focus on a subject and recompose by just panning the camera around, then that would cause your subject to be somewhat out of focus but still sharp enough that it is undistinguishable. However, if you compensate by it by moving the camera backwards a little bit to keep the same distance prior to recomposing, then the image will be as sharp as it was as if you didn't recompose.
All cameras, despite the brand name, will have this problem unless your camera already backfocuses in the first place which in turn would make the image when recomposing, sharper compared to not recomposing. Hence the settings on the camera that allows you to adjust for focusing compensations.
But yea, good for you that you are not having any troubles. No need to tell the world. Physics works the same way for everyone. Your expectations are different from everyone else, so what you see as sharp may not be sharp compared to other people.
