We Must Speculate. . .
The problem with trying to ascribe murders to a specific unidentified killer is that we are often forced to make assumptions.
In terms of the wounds, the Nichols and Chapman murders were very similar. Given the extreme nature of the attacks, it's difficult to believe that two different people carried out almost identifical murders.
Beyond that, we are into guess work. While we can link certain murders together based on modus operandi (location of victim and wounds), we must also remember that are instances where methodology radically changes.
Peter Kurten, the Dusseldorf Ripper, used a wide variety of methods to attack his victims. Abberline suspected George Chapman - who was a poisoner.
What some consider using "logic" to determine this question are really engaging in "probabilities." Once these are multiplied against each other ("he probably didn't have time to mutilate Stride" "he probably was unsatisfied and frustrated so his attack on Eddowes was more ferocious than the others") the possibility for error increases.
