Your comparison is simplistic at best. Were both mirrors of the same quality? Do both scopes have the same amount of light baffling? Were both scopes completely cooled to ambient temperature?
Unless you took those things into consideration, your comparison is meaningless. There's no way that a 10" scope will show the Trapezium to be sharper than in a 12.5" scope unless the latter is of inferior quality.
Nice try, but no dice.
