Once you know that you know if the problem is in mashing (low attenuation limit), fermentation (ok or high attenuation limit but low final beer attenuation) or both (low attenuation limit and large difference between that limit and beer attenuation).
I do this test for all my beers and it is one of the most useful tests you can do that’s out there. Nothing beats knowing where your FG will be 3-4 days after brewing.
This is a good idea- even doing it now with fresh yeast should help me find out if I just have a stuck fermentation or if I mucked up something in the mash. I'm going to start doing this for my future brews as well. It'll give me something to check instead of poking at the primary fermenter
