How can two divisions in the same year have such different values?
One more quick thought on this, with more to come later:

Both 2014 galileo and newton sCPR searches picked VarN/VarO=3.

If VarD/VarO = 0, then the total match variance would be 3*VarO + VarN = 6*VarO.

If on the other hand VarD/VarO = 0.1, then the total match variance would be 3*VarO + 3*VarD + VarN = 6.3*VarO.

So while this looks like a really different result, we're only talking about a change in about 5% of the overall variance in a match that could be predicted with VarD/VarO being 0.0 or 0.1. Instead, it might be helpful to increase the step size in the VarN/VarO search, which is currently 1 (!), so each step in that search could cause a much greater change in the match variance.
