Hi Richard,
Your method is fine also, but using your method assumes that I had 2 batteries where I only had 1. Also it would require my lazy butt to still have to take the grip off each time I charged the battery to reverse them, so it didn't solve anything for me.

As for it being a problem, I don't think so. These batteries do have a finite number of charges in them, but they don't have charge memory like older batteries. And that finite number of charges will be used up regardless of the battery being in the camera or the grip.

If I had 2 batteries, I probably will would only have kept 1 in the Grip and carried the other in the bag and just rotated them out. But that's just me, there is no right/wrong here.
