100% crop w/ kit lens and 5N. Sample of f/5.6 v. f/9, f/9 being softer. Same results for the set I shot at 28mm. This is easy enough stuff to check for yourself. All you need is a well lit target, camera, and tripod. I used the remote release for this, OSS off. f/10 looked softer yet. Since OP is looking for sharpness improvement, this along with other good techniques mentioned can help.

Focus point is on the notes under the D7 pencil mark.

I am very amazed at this statement. As far as I know and for APS-C, the diffraction limit is between f11 and f16 (closer to f16).

But I admit not being a specialist on the subject, so it would be interesting if you can explain what sustains your claim.

For one, stop shooting at f/9! It's above the diffraction limit, and IQ starts to degrade. Shoot at f/5.6 or less.

I agree, f/9 is not above the diffraction limit.
