Not to blow up any heads, but it's just a math model and your "Surface GF" number on the computer knows nothing about your actual body state.
Ascend slowly, pause and enjoy the shallows before finishing the dive. Call it whatever you want.
If you fully believe in the GF theory, look at how much it spikes in the dive log when you go from ~5 or even ~3 meters to the surface. It's usually the highest spike in most people's dives.
The PADI style rigid safety stop is great for pausing ascents and regrouping divers so that the DM can SMB and make sure people surface together, so they don't get scattered or run over by boats. If they really cared about DCS it would be 6m/20ft & 3m/10ft safety stops, at least three minutes per.
Another problem with safety stops is when the insistence of doing them exposes you to highly increased other dangers, such as getting carried away in a current, delaying critical care to a distressed diver, or even delaying the ability to access oxygen on the surface etc.
