Your "scientific" method is just as shaky then. You assume that just because Dio and Jotaro have similar Stands that the fight will go the same way and ignore that knowledge of the enemy's power has a tremendous impact on the result of any fight, ignore that Dio and Jotaro have not the same personality and fighting style, think that Jotaro can just deduce the nature of Tusk's power just by watching and so on.

Johnny canonically has had experience with time Stands because of Mandom, Jotaro has none about Spin. When Johnny shoots, Jotaro only sees a spinning nail: either he blocks the nail and is screwed or avoids the nail and then still doesn't know that the Spin can still go at him, screwing him again. On the contrary, Johnny can stay out of range of Jotaro if Jotaro uses time stop even once, because he can deduce what's happening thanks to his knowledge.

Even during the canonical Dio v Johnny fight, we see that Dio's knowledge of Tusk allowed him to avoid being touched at least three times. That was three potential victories that were averted because Dio knew the power.
