Rojo: whether or not this was fake, one of your arguments does not make sense.
Yes, the odds of tying, say, a marathon record to 1/100th of a second are very small. However, for a 40m dash record, the "window" of expected times was probably 4.10 (Christian Coleman ran 4.12 in a real attempt with spikes) to 4.30ish (that's already outside the top-10 40m times). There are only 20 increments of 1/100th seconds in this interval, so even with a flat prior, it's not at all improbable that two times turn out to be exactly identical.
Of course, it is possible that Bolt ran much slower. But from a purely statistical point of view, the fact that it was an exact tie is not significant.
