why the three sets are more accurate than the two sets when generating initial layout with MDS alogorithm??

The MDS algorithm should be basically perfect with 2 sets as well - but I was running into some numerical stability issues with the SVD implementation I was using from numeric.js. I remember investigating and finding that certain inputs were getting NaN values from numeric.js (but passing the same values to the svd implementation in numpy worked fine). I didn't worry about it too much since I found better methods than the basic MDS algorithm
