The Wikipedia article does not support your argument. It merely relates the history of the bifurcation primary driven by differences in script and religion. I am well versed with the history of Hindi and Urdu going beyond this Wikipedia article. If you want to make your argument rigorous please give an estimate of pure textbook Hindi speakers (people who use avashya instead of zaroor, hriday instead of Dil outside academics and newspapers) and "hindustani" speakers. My conservative estimate is less than 10M for "pure Hindi" and greater than 300M for regular hindi/Urdu. This is because virtually every one from North India and Pakistan speaks the so called Hindi/Urdu mixed language. I have also met bhojpuri, awadhi, marwari speakers but I am yet to meet the mythical pure Hindi speaker and I am a really old guy.
