the claim

Projectile time of flight on an inclined plane equals twice the time to maximum normal distance due to symmetry.

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that Projectile time of flight on an inclined plane equals twice the time to maximum normal distance due to symmetry?

The time of flight for a projectile on an inclined plane equals twice the time to reach the maximum normal distance because the trajectory's acceleration and deceleration perpendicular to the plane are symmetrical.

The analysis

The claim states a fundamental kinematic property of projectile motion derived directly from the symmetry of constant acceleration under gravity, making it a matter of basic physics common knowledge that does not require empirical citation.
