I always coach 6 beat in the pool but i do have one junior that swims an effective 2 beat so haven’t changed it. 6 beat is 3 kicks per arm pull. I always point to Solar Energies swim waltz video. I actually took it to a BTF course and its now doing the rounds of the UK 
If only he was still around to know hes inspired some of the best coaches in the country!
