◆ greaterWithBias()

static bool greaterWithBias	(	BlockFrequency	A,

static

Compare 2 BlockFrequency's with a small penalty for A.

In order to be conservative, we apply a X% penalty to account for increased icache pressure and static heuristics. For small frequencies we use only the numerators to improve accuracy. For simplicity, we assume the penalty is less than 100% TODO(iteratee): Use 64-bit fixed point edge frequencies everywhere.
