Had this reflection that 144hz screens where the only type of screen I knew, that was not a multiple of 60. 60 Hz - 120hz - 240hz - 360hz

And in the middle 144hz Is there a reason why all follow this 60 rule, and if so, why is 144hz here

    I had huge 100mm wheels, so I thought I felt the difference between ABEC-3 and -5, but maybe that was just placebo.

      To quote Wikipedia:

      The ABEC rating does not specify many critical factors, such as load handling capabilities, ball precision, materials, material Rockwell hardness, degree of ball and raceway (cone) polishing, noise, vibration, and lubricant. Due to these factors, a high-quality ABEC 3 classified bearing could actually perform better than a lower-quality bearing which satisfies (the stricter) ABEC 7 requirement.

      ABEC only rates tolerances. Nothing else. They were rated bearings you had so they performed better than chinese knockoffs. If you wanted good stuff, go with Japanese, German or Korean.

      I could be wrong and really don’t have the math in me, but I believer we’re taking about thousands of RPM here
