I am assuming you selected the Pitch Series specifically? Your business plan is a hypothesis and whether you prove it inductively or deductively in the Pitch is moot. Regardless of your line of reasoning it is requisite that you provide the proof in a short slide series (probably no more than 20-40 in Series A).. Although a detailed plan will be required, Series A is generally considered an Apéritif if I may use that analogy and if you spend a great deal of time describing every proposed course thereafter, it's proper pairings, your rationale for them, the historical rationale, the nutritional value of each and the Digestif, my guess is you will lose your audience.
I have read that those who have authored books often write the Preface after the entire book hence the Series A Pitch, like a Preface, will need to be grounded in fact and detail which follows in Series B. and thereafter.
However rather than provide a 'point-counterpoint ad ad nauseum' why don't I just refer you to what other experts have said on the subject responsive to the scenario you provided:
