    Chrono scores

    Hi guys

    I am currently trying to put. Database together (at my club). For limb speeds

    So,. If anybody has any chronograph results that they don't mind sharing I'd be very grateful.

    Information I'm looking for is
    Limb make / model
    Limb poundage
    Arrows used
    Arrow spine
    Arrow length
    (Weight if known would make life easier for me)
    Archer draw length

    Once I have finished gathering data (which may take awhile as we have a lot of limbs to shoot the the chrono). I'll be happy to share the v results.

    Thanks

    Mike

    Hi Mike
    For accuracy you'll also need to know the weight on the fingers

    And make sure the arrow spine and bow are set up correctly.... can of worms

    Also String material, number of strands, tab make and face material and how good the release is I have seen people lose or gain 4fps with a bad release or good release.

    Good luck with getting meaningful data - one of the reasons manufacturers don't publish this data other than this years limb is faster than last years by now we must be up 1000 fps - bit like golf clubs 20 yards each year 20 years we must be over 800 yards by now

    Yeah very true, but some rough numbers are better than no numbers

    Thats why i am asking for drawn length, so it can be calculated rather than the usual (about xx on fingers)

    How are you going to take into account the tiller bolt position, that can easily be a 10% drift.
    10% is a hell of a lot when your comparing limbs for speed.
