I like this discussion. Let's not limit it to the vacuum theory as the Original Post makes a comparison of only neglecting air resistance versus air resistance. Nothing is said about being in a vacuum.....
Let me ask this, as I shoot a lot of Cap and Ball. And maybe this will get us back on track with the OP...
Let's deal with sphere's....both fired horizontally at 6'....at the same weight and at the same velocity.
In Case 1: Negative Air resistance.
If I over spin a ball, it would still go straight and would have the same flight time before finding ground as a underspun ball.
In Case 2: Adding Air resistance.
Same overspun ball that slices upward through the air (as in a golf ball slice) And a underspun ball that just goes straight....
Obviously the effect of air resistance comes into play as the overspun ball gains altitude....
Do you think there would be.....no meaningful effect still?
