Well try any set of inputs which require normalisation. You'll find these no
longer get normalised and so will get incorrect results. Try basic cases like
1.0 - 0.75 which I think will return 0.625...
A basic test would be to run old vs new on a large set of inputs to verify
there aren't any obvious differences.
