Yes I have the same thing hapening when I do a large water change and I have to cut off my dosing pump for a few days until things gets lower. But if your alkalinity is 7 and you change 50% or the water with alkalinity 11, that should bring it to around 9, so if you change 25% it should only be around 1 point so not that big of a change.
Still, one point is sometime enough to disturb sensitive coral but I had swing going from 6 to 8 in one day before I was using dosing pump and I never lost a coral from that.
I too wish RC would be more around 8 in alkalinity since I am dosing.

Every now and then I like to do a larger change though and this is when It's a bit annoying.
