This is not a general statement. It just happens to work for some problems when parameters are neither tiny nor huge.

There are always tradeoffs.

1. Uniform sampling simplifies the math. However some times the mesh size has to be too small to characterize all of the important info. In those cases sometimes nonuniform sampling is the better choice.

2. Mathematical accuracy tends to improve when parameters are restricted to certain intervals. Whether or not normalization is useful depends more on the extent and variation of the original measurements and parameters.
