Subject: Definition of branching factor?

Hi!

What is the definition of BF and how is it calculated (this has probably been
discussed N times, but...)? Now I'm calculating like this:
              ______________________
BF=(DEPTH-1)|(Nodes/root_move_count)

So it means (DEPTH-1)th root.

Example (from Vincent's position): DEPTH=9 plies, Nodes=2'000'000 and we have 38
legal moves in root.
     ____________
BF=8|2'000'000/38 = 3.9

Could this be close to the truth?
