    This thread can be used to discuss the inaccuracies and issues concerning weigh-ins.

    In particular, I made this video to address the Darren Till "trick" that is common in many threads.

    As you will see, even a slight change in level ground can effect the reading because the load cell
    is made to measure force in a perpendicular direction, not angular. The circuit for a digital scale uses
    four load cells to average the platform.

    If you only used one cell in the middle of the platform, the tilt would cause irregular readings.

    The commission needs to have a spotter checking fighter stance on the scale to be centre,
    and standing straight. This is how the load-cell (strain gauge) is calibrated).


    In my video the scale reads a one-pound differential just by moving it a few feet away to
    another area of the floor. I was able to get a few pounds by stepping back like Darren Till.

    This goes for any digital scale, no matter how expensive, or inexpensive. They all use
    similar technology.




    Errors in Accuracy:

    Leveling the Scale
    If the scale is off balance, it will cause an incorrect weight. Test the location of your scale to be sure that it is sitting on a level surface, and check that the scale’s little feet are all on and even. Also turn the scale over from time to time and clean the bottom since too much debris might interfere with the way the scale sits.

    You disagree?

    I changed the weight by 1 pound by moving the scale location on the floor, and three pounds by tilting
    the scale back.

    That's pretty significant, don't you think?

    Sorry, wasn't paying attention. I fucking hate portrait videos too! Maybe I'll redo it... : /

    I just tried my scale. I even put a koozie under one foot and it read the same weight. I put on hardwood floor... the same I put on carpet... the same. I think your scale sucks maybe.

    Or maybe your scale is not sensitive enough, or not using strain gauge / load cell like the UFC scale.

    Show a pic / video. Curious to see how it reads the same on carpet and hardwood. If it's not level and
    still reading the same value, it's likely not load cell technology.

    It doesn't matter what my scale says or yours. You would have to test the same scale they are using and on that same location on that floor they weighed in on. Im not taking pics or videos because its not that interesting and im chillin

    Using some cheap home scale and moving it to change the weight proved what?

    Think fighters magically know which direction to kick a scale and make it read less rather than more?

    Props for taking the time to write this up.

    Regardless of whether Till was actually able to cheat the scale, it seems like he at least tried to. Seems plausible that he could get it to read a pound or two off.

    Dudes most digital scales have this thing.. here is the thing if the commission doesn't want to 'help' you out they won't read that lower number they see they will make you stay put on 2 legs and not move until that sucker is showing a number that isn't changing/oscillating.

    If the commission is loosey goosey then they just read the lowest number and be done with it.
