    Voltric 70 = 27lbs by 28lbs, BG66 Ultimax = 1295Hz straight after stringing
    Does this sound correct?

    Still, I'm confident - my WISE is spookily accurate.

    Thought I'd move the discussion to this frequency thread instead, since Darth already answered me here. He uses 10% more on crosses with 10% prestretch. But he says he's a slow stringer, meaning his string is subject to constant pull longer. So may explain his frequencies which seem 1-2 lbs higher than what I've seen.

    Thanks visor. So for the bg65 it is not that far off my experience, if he stringing for example 27 is 27/30. I don't think the time is factor 30mins isn't slow is it?

    well, these tensions are easily 2 pounds over what I get. I've never had BG65 come close to 1351hz and certainly not under 30lbs

    Anyways, as long as we're consistent right :P

    I'm not saying if i'm right or wrong...but that's the data i'm getting when i record the frequency within 5 minutes of finishing a string job. I think the numbers will fall closer to what visor is getting if i wait 24 hours. I'll have to measure when i get a racket to string.

    I have checked that the wise is calibrated correctly. 30 minutes is my best...35-40min is more the norm when i string. Some people have mentioned that i string "tighter" than others, but like all good stringers, i always ask for feedback such that the next job has more/less tension.

    Stringing Top Down on crosses, 4 knots:
    27 on mains.
    For the top most cross (where my starting knot is) i tend to only tension at no more than 23 lbs (especially when the string guage is thin) becuase i've seen it snap on me if I tension any higher.
    28 on the next 3 crosses and 29.7 on the subsequent crosses.

    I prefer not pulling both top 2 crosses since the tension is halved(i remember kwun doing an experiment on this)

    Oh I'm not trying to find whose wrong, just saying my frequencies aren't that high, even right out of the machine.

    Right ok thanks. Like blableblibloblu said my purpose is not to proof you wrong. Just curiosity with your stringing. I too measure straight after with carltune (just to see consistency). When I do 27, I do mains 27 and all of the crosses 29. I make sure it is pulling right tension and mark string to ensure no slip is on clamps. for BG65 always comes out about 1190hz, quite a way off yours, just wondering how could be.

    Going slowly doesn't necessarily mean longer pulls, and if you're a slow weaver that'll mean more tension loss by the end.

    Personally, I leave my strings pulling until my WISE stops chattering (which is normally a couple of seconds after the beep).

    What's behind slow weaving and tension loss?

    No worries. I'm trying to understand the variation too. 1275 HZ average compared to 1190 HZ when job is completed is quite the difference for BG65 @ 27lbs. The interesting thing is the data has been relatively consistent even though i changed fixed clamps.

    Might be my technique.
    I'd love to shoot a youtube video...but i think you'd all fall asleep watching me string...

    The thing is I just can't see where I would be losing tension/frequency over you. The rackets you string, do they come with tiny heads before you string?

    I wouldn't jump to the conclusion that you are losing any tension. It seems that i'm the outlier here.
    What i may need to do, is shoot a video with my calibrator, and then shoot video of me stringing a racket. The analysis will go from there.

    Forgive my poor humour...I don't get the last statement.

    The smaller the head the higher the frequency. So if the calibrator is correct that is the only thing left.

    Some of the Rackets i've strung that are included in the data:
    Li Ning N90 II/III (BG-66 UM/BG-80 Power/NBG-99 @ main of 25 or 26 lbs),
    Yonex Voltric Z-Force (1, 2 and Limited - BG65 @ main of 27 lbs),
    Victor Meteor X JJS (my primary racket - zymax 65 with main tension of 25lbs),
    Yonex AT-900T,
    Victor Bravesword 9 (BG 85 with main of 23), 12, LYD,
    Yonex Voltric Z-Speed,
    Fly Power Arbi El Nino (BG-65 with main of 26 lbs),
    Victor Thruster 9000,

    Yeah sorry just my poor humour, none of those rackets are nearly small enough to get my frequency up to yours.
