There's a minor issue with the calculations. It should be:

    60 * 445 / 216.276 = 123.453365145
    
    60 * 445 / 216.282 = 123.449940356

Not the other way around. And since the timing is only given with millisecond accuracy, the bpm should be rounded to the same number of significant digits:

    60 * 445 / 216.276 = 123.453
    
    60 * 445 / 216.282 = 123.450

So, it's the YouTube version that's 123.45 bpm to within the rounding error.
