    Default CONTEST: Guess the tension loss (with MORE PRIZE!!!)

    imagine the scenario when starting cross strings at B9->D9.

    1) if i tie off on B8 or B7. and pull 30lbs at D9. what is the tension outside B9?

    2) if i weave 2 strings B9->D9, D10->B10, then i pull once at B10, what is the tension outside B9?

    answers must be in pounds of tension and must be a single number and not a range.

    the formula for closest will be the sum of the absolute of difference.

    the value will be taken from measurement from my machine. the value will be taken 1 minute after my WISE beeps to let the tension settle. setting will be fast speed, no pre-stretch, constant pull.

    The PRIZES

    - one Li-Ning Performance Shirt
    Sponsored by www.badminton-nation.com

    - one package of the new Yonex NBG99
    Sponsored by www.mybadmintonstore.com

    - one 10metre length of Zymax String of your choice (ZM62/65/67/70)
    ZM62 will be cut from a reel. ZM65/67/70 will be a package.

    (i might add more prizes later if i can find more sponsors)



    DEADLINE IS 11:59pm PST, Saturday, March 31st.
    The answer will be revealed in a video of the measurement.

    I'd take a wild guess and say:
    1) About 27-28 lbs
    2) About 24-25 lbs

    actually, to make this more fun. i am going to add a prize for one who gets the closest answer.

    the prize will be 10metre length of Zymax String of your choice (ZM62/65/67/70)

    ZM62 will be cut from a reel.
    ZM65/67/70 will be a package.

    the formula for "closeness" will be the sum of the absolute of difference.

    the value will be taken from measurement from my machine.

    Is pre stretch on?

    #2 Please define double pull. Is it
    1) Pulling string on B10 at 30lb till your regular tension head stop?
    2) Pulling string on B10 at 30lb. release then pull it again at 30lb till your tension head stop?

    Thank you.
