The problem isn't tasking, it's decomposition.
If the "lengthy function" cannot be broken down then there are only two 
points that we can really know: start, and finished. (i.e 0.0 & 1.0)

If, on the other hand, we can break it down, say into eighths, we get:
0.0, 0.125, 0.250, 0.375, 0.500, 0.625, 0.75, 0.875, 1.000
Which is n+1 states, where n is the cardinality of the resolution of 
"breaking it down". ( As an example regarding DB-access/-processing 
being so decomposed, watch this:
