Here's the thing, if you have no idea what their plan is, is it your fault for not understanding it or their fault for not articulating it well? I submit the pgbot scenario provides a third alternative: people can't understand their plan because it makes no freaking business sense.
And whatever that original plan was, I'd bet the pitch didn't include a PowerPoint slide point along the lines of "Two months after we go public, the president leaves and sales really take off!"
