    The buss cable and the control cable work in OPPOSITE directions, to get the SAME effect,
    which in OUR case, we wanted to make the top cam hit FIRST earlier and earlier...cuz we STARTED with a MASSIVE gaP on the top cam,
    and we wanted to make the GAP between the top cam and the cable, at full draw...smaller and smaller,
    until the TOP cam hits FIRST by a tiny amount.

    Is this ******ing or advancing?

    Don't Care.

    Since you have NO adjustment remaining in the control cable, to make the control cable LONGER, and you still have a GAP on the top cam.
    You can go the OTHER way, and make the buss cable SHORTER And SHORTER...cuz, this is the SAME effect as making the control cable LONGER and LONGER.

    So,
    you now adjust the buss cable SHORTER and SHORTER and SHORTER,
    and even though you are not DIRECTLY adjusting the control cable, the control cable behaves LONGER and LONGER
    and the gap on the top cam gets SMALLER and SMALLER, until you FINALLY have the top cam hitting FIRST
    and you have a tiny gap on the bottom cam, equal to the thickness of a credit card.

    Soooo,
    did we ADVANCE or ****** the cams?

    No idea.
    DON'T care.

    IF you make the buss cable shorter and shorter and shorter,
    this makes the control cable BEHAVE as if the control cable is LONGER and LONGER, even though you did not touch the control cable.

    IF you make the buss cable LONGER and LONGER and LONGER,
    this makes the control cable BEHAVE as if the control cable is SHORTER and SHORTER, even though you did not touch the control cable.

    So,
    you untwist the control cable LONGER and LONGER, cuz the bottom cam is hitting FIRST, and you have a MASSIVE gap on the top cam.
    YOu want the top cam to hit first. YOU have nearly ZERO twists in the control cable.

    NOW WHAT?

    Well,
    simple.

    BUT

    BUT

    I heard on ArcheryTalk to work the cam TIMING with the buss cable.

    NO,
    I heard other people on ArcheryTalk say to work the cam TIMING with the control cable.

    Who is correct?

    BOTH are wrong, and BOTH are correct.

    The buss cable and the control cable are kissing cousins.

    For a hybrid cam system, for MOST folks...even cam SYNC...both cams hitting at the EXACT same moment, does NOT give you the FLATTEST arrow group size.
    You must take the hybrid cams OUT OF SYNC...on purpose, to get the best results..to make 2-inch tall group size into a 1-inch tall group size.

    To get groups like THIS at 20 yds....you must get the Hybrid cams OUT OF SYNC...on purpose. Only question, is how much OUT of SYNC. It varies for EACH shooter.
    Did I advance the cams? No idea.
    Did I ****** the cams? Don't care.

    Work the cams OUT of SYNC...on purpose, for BEST results.

    If the bareshaft and FLETCHED arrow are NOT in the SAME hole..

    if the bareshaft is missing the FLETCHED hole by 1-inch high-low...if the bareshaft is missing the FLETCHED hole by 2-inches high-low
    when firing from the 10-yard shooting line....WORK the control cable...(ADD or REMOVE 1/2 twist).

    MOST folks get pretty good results, with the top cam hitting the cable FIRST, and a tiny gap on the bottom cam, equal to a credit card thickness.

    FROM this starting point, you will be half a twist away from YOUR PERSONAL sweet spot, for cam SYNC...(not cam timing).
    You might be one FULL twist away from your PERSONAL sweet spot for CAM sync...(not cam timing).

    SHORTEN or LENGTHEN the control cable just a half twist, and you have a NOTICEABLE change in cam SYNC...(not TIMING).
    SHORTEN the control cable just a half twist, the top cam hits LATER and LATER, compared to the bottom cam...for each additional half twist adjustment.
    LENGTHEN the control cable just a half twist, the top cam hits EARLIER and EARLIER, compared to the bottom cam...for each additional half twist adjustment.


    WHY change the twists in the control cable by just a HALF TWIST?
    IS this advanced or ******ed? Don't care what the lingo is.
    I only care about RESULTS.

    10 yards.

    SHORTEN the buss cable, the draw length gets longer.
    LENGTHEN the buss cable, the draw length gets shorter.

    SHORTEN the buss cable, the holding weight goes DOWN.
    LENGTHEN the buss cable, the holding weight goes UP.

    SHORTEN the buss cable, draw weight goes UP.
    LENGTHEN the buss cable, draw weight goes DOWN.

    SHORTEN the buss cable, the brace height grows a tiny amount.
    LENGTHEN the buss cable, the brace height shrinks a tiny amount.


    SHORTEN or lengthen the control cable, the usual amount of half a twist or one full twist....ZERO measurable effect on draw length.

    Bowstring.
    Bowstring controls draw length.
    Bowstring also controls holding weight.

    SHORTEN bowstring, draw length gets shorter.
    LENGTHEN bowstring, draw length gets longer.

    SHORTEN bowstring, holding weight goes up.
    LENGTHEN bowstring, holding weight goes down.

    SHORTEN bowstring, draw weight goes DOWN...that's right, you LOSE draw weight.
    LENGTHEN bowstring, draw weight goes UP...that's right, you GAIN draw weight, when the bowstring stretches or when you remove twists.

    SHORTEN bowstring, the brace height grows a tiny tiny amount.
    LENGTHEN bowstring, the brace height shrinks a tiny tiny amount.

    I don't use "******" or "advance"...cuz folks do not agree what direction of cam rotation that means.
