Shelf-life of mass-tag stained FFPE slides

Hi, we are about to start on a TMA Hyperion project. We won't be able to and don't want to ablate all of the cores immediately.
So far we've always ablated within a week of staining. Does anyone have experience with or has anyone done experiments to check for the shelf-life stability of stained slides?
I've heard "a long time" but we'd like to know more specifically. Does that mean 6 months or 6 years? What happens if you ablate after the recommended time? Is it a small signal drop?
Any insights would be much appreciated!
