What is your ALK?

I tested my tank levels last night before and after a 20% water change and here are my results with OPP.
Before/After
CA 460ppm/520ppm
MG 1310ppm/1380ppm
Alk 7.4KH/7.4KH
PH 8.035/8.12
I was surprised that my ALK didn't change after the water change, but reading above that OPP tests at 7KH itself makes my results valid IMO.
