I have been trying some different roasts in my SA, and I was wondering how long it takes to get the residual coffee from one blend out of the grinder so that you are getting an accurate sample of the blend you are replacing it with?

Edit:
To make myself more clear, I have run the grinder until no beans are left in the grinder, but I assume there is small amounts of coffee that will remain in the grinder blades for some period of time. My question above is how long does it take to when you are grinding a different blend does it take before you are getting a relatively pure sample of the grounds from the new blend that is not contaminated by the grounds from the blend you are replacing... I hope this is making sense.

100% guessing here.  Likely by the 2nd shot.

Many things would affect it including roast level of beans and how coarse the grind and what type of machine.  One would assume that the grind retention would be such that the first shot would be contaminated, but likely not much by the second.

depending on the size of your chute
most of superauto machines have the next shot basically in the chamber waiting
so I will say that after 2 shots you should be ok
or
clean all the beans
run the grinder until "empty"
clean the best you can and introduce new beans
