    When you put your arrow length (30 inches) and draw weight (34 pounds)in to the Easton 2011 shaft selector app it gives a result for ACCs' of 620. Your mistake was using draw length instead Of arrow length.
    there is a cheap way to tell if the recommendation you have for your shafts is correct and that is to buy two alloy arrows from the same group in this case 1916's ( 623 as opposed to the ACCs' 620) bare shaft tune with just the two alloy arrows. If you get a good tune then go ahead and buy a set of 620 spine arrows. Get another couple of alloy arrows and use the alloys indoors.
    just point,pull & squeeze the trigger

    personally I cant get on with the match in the plunger thing, so I always use the Simon Needham tuning method, which would be worth a try....

    Take the match out of the plunger and set to a medium tension
    Check centre shot,
    align the sight pin directly above the centre of the arrow and don't touch it
    Shoot fletched arrows and adjust button pressure to centre the arrow group on the target
    Once the group is centred, shoot mixed fletched and unfletched arrows
    Then the position of the groups will tell you the spine but taking into account the effect of the button.

    I do agree though that you probably do need 620 spines. The Easton chart is very confusing that if you already have arrows you need to use the actual arrow length, not the AMO length.
