How about not looking at other teams records and what is possible based on that? Here's a radical suggestion instead....
Do you believe that Aberdeen, if all the factors that I listed previously were in place, would be able to achieve a record of 28-4-2 against the non-uglies?
Base your thoughts on that and if you still don't think we could get close to that record then maybe best you go follow a team with limited ambitions, United or similar.
