RNG and Global Timers

Mega Man 10's RNG is mostly* determined by time since stage start. This means some randomness can be pre-determined by how long it takes to reach a point in the stage by the frame. Since frame perfect movement over long periods of time is nearly impossible, there are 3 points in the game this is relevant. 
 * Some of it is also depends on destroyed enemies
