Let me be more specific about the other grits.
The finer finish can be sharper but it depends on how its executed.
It's very very easy to "round" the apex moving up the grit
The mirco convexing is due to slight angle inconsistencies that add up and Evently "blunt" the apex
You'll be confused because the finish looks great but it will cut horrible.
These edges are working at a level beyond what the human eye can see.
But the paper never lies
If that edge doest bite when starting a push cut that's a rounded apex.
It takes great skill to prevent rounding the apex with a mirror finish
And lots of time.
Now you see a mirror finish doesn't always equal more performance.
And even when well executed, the performance can be marginal unless it meets a specific cutting job I.e shaving or cool factor

"sport edges"
What do you do if you round it?
Go back to the last grit, increase pressure, finish with lighter pressure and continue with focus to hold the same angle
I don't use the other fine diamond plates unless my objective is a mirror finish.
Otherwise , jumping up the ceramic does an amazing job refining the apex (removing any remaining burrs and debris on the apex)
Stropping really takes the edge to more refined state.
But too much pressure on the strop and your back to rounding the apex.
You didn't waste your money on the upgrade kit.
You got the most important diamond plate for reprofiling and the strop for making some killer edges
You also have the option to make a mirrior polished bevel.
It's nice to have options.
Hope that's not confusing
Thanks for your interest.
