in time with the drum it's L, L, L, R ... then count with the drum as they chant 1, 2, 3, 4 without pushing anything. Then L, L, L, R, again in time with the drum etc. So between your four button pushes, in time with the drum, you wait four counts before beginning your push button sequence again. The complete sequence is eight counts, first four pushing L-L-L-R and then counting 1-2-3-4 as they chant back to you, rinse, repeat.
