Comment (by gp1308):

 >So dicecoefficient(Q₁, d₁) = (2 * 2) / (2 + 5) = 4/7 (not 0.5)

 Thanks, You are right, copy paste mistake.

 > You could invent some elaborate system for them to share the value
 rather than recompute it

 Initially, I thought of using the scaling factor for this purpose. It
 doesn't seem right.

 As you mentioned, computing the denominator every time seems the right
 way.
