How far any practicable differentiation between the various Sant Mat,  Radhasoami and associated groupings can be made is open to question. It's a bit like trying to decide what diffences there are between the two ends of one piece of string.

Classifying Rawatism as Sant Mat rather than Radhasoami does not,  in my view, advance the understanding of Rawatism very far because neither Rawat nor his followers will admit to the religious implications that such classification would have. And this is one (of the many) problems of the Wikipedia approach - without an incisive and critical investigative approach one is just left wallowing in  the 'sugar candy' of Rawat's propaganda.

Here's a Hindu perspective on Rawat from 1983:
