There's a very sage article by Derek Jones on R22 training in the latest edition of AOPA's 'General Aviation' magazine. The bottom line for him on EOLs is that they are 'better...demonstrated from an early stage and later practice the relatively simpler gentle single flare to a run-on landing with at least ten knots of wind through the disc.'

At risk of repeating what I've said on other threads before, PLEASE do not try experimenting with anything contrary to limitations or advice in the helicopter Flight Manual. If you deliberately go right to the edge you may fall over. Those of us who do this for a living have been extensively trained to do so and work in a highly risk-managed environment.
