2 things wrong, 1 don't link to the ftp, and 2 that's the wrong demo. because i feel there was some abuse here i'll post the demo.
ticks: 40300 (slaps to get ahead of the main pack of teammates), 50200 (slaps to get up the elevator shaft faster), 52500 slaps to his death. none of these gave him a real advantage in the end, he was in no real danger from zombies and he never got too far ahead of his teammates, however he did spam slap to move faster at certain points.
