Data rejection will work better if you register with nearest neighbor.

I haven't always had this. I am wondering is it time to take fresh darks, or is it my change to CCDStack 2 versus CCDstack. Nearest neighbour is now an option in CCDstack 2 and I don't think it was available in CCDStack.
Hot/cold pixel then impute/interpolate will take care of those residual specks. Nearest Neighbor was already available in previous versions of CCD Stack. That's the registration algo I've always been using.
