TF2: Sentry rocket damage falloff is calculated based on the distance between the sentry and the enemy, not the engineer and the enemy

The statement is false because in Team Fortress 2, the sentry rocket damage falloff is actually calculated based on the distance between the engineer and the enemy, not the sentry itself and the enemy. The engineer's proximity to the enemy determines the level of damage reduction, with the falloff increasing as the engineer gets farther away from the sentry. Therefore, it is crucial for the engineer to stay close to the sentry in order to maximize its damage output.
