I'm not sure, but maybe the K in K- #QuasiConformal is the same as the #ConditionNumber:

$$K = \frac{\max_k{|\lambda_k|}}{\min_k{|\lambda_k|}}$$

where the $\lambda_k$ are the #Eigenvalues. That gives me a bit more of an intuition I suppose...

Now to try to get #maxima to calculate it for my particular functions of interest
