                // One may notice that this is still not the most precise
                // method since a frame takes up the time its sectors took
                // up instead of the amount of time it takes the next frame
                // to be read from the sectors. The actual frame rate should
                // be constant instead of variable, so the slight difference
                // in a frame's showing time is negligible (1/150 of a second).
