I can imagine some reasons: - They don't care about performance and think their users don't care about performance. - They have sold something that doesn't make sense but sounds good. - They are afraid of their users. - Their users don't understand the problem you're describing or simply don't believe it. - The business domain of their users actually knows the about the issue, but they still want or need the exact counts.
