How are branching factors calculated? I get wildly different values at each ply
as each side usually has different numbers of moves available to them... and at
the root node, its always the full number of moves isnt it?

e.g, for 8/6k1/6Pp/3r1P2/6K1/n3BP2/1p6/4R3 w - - 3 51
I get branching factors at each ply of 26 2 20 4 16 3 13 3 10
