Hey guys - I know we've had threads about this move before but am wanting some advice from you card experts out there

The initial push up, with the right hand palm - I'm guessing this has to be SUPER light to achieve the right results?
Pulling the card underneath down with the bottom of the palm - my hands are by no means smooth but am having real trouble with this
Also - I sometimes push more than one card up and drag more than one down!
Have been practising this for months and don't really appear to be getting anywhere...peoples thoughts?!
