Voltage drops

So I replaced my alternator nearly a year ago but recently I've been monitoring the voltage and I have noticed that occasionally while im driving, my volts would be 12.2v-12.3v and once I get to 4k revs and above then the volts go back to the 13v+ this also happens when I am in gear and let off the accelerator and coast, volts shoot back up to normal when I do that.

The belt doesn't seem to be slipping and grounds seem to be okay, anyone else experienced something similar or know how to fix this as it doesn't seem right. Never had any issues with my battery being drained flat.
