I agree here, stated value on the wrapper as motors could be plus or minus rpm. I’ve purchased multiple motors from the same manufacturer and NONE of them ever hit their stated value while others were dead on in both directions and a mere one or two were outliers. I also don’t think everyone tachs their motors prior to use, after break in and after extended use. I found on occasion if you throw parts together without regard to anything but the wrapper, you could end up winning a few races.
