First note is perfectly possible. Note held too long? Tempo too slow. Note released too early? Tempo too fast, or note erroneously played staccato.

A 10% change in tempo at 120 BPM results in a difference of 50ms in the duration of a quarter note. This is certainly not difficult to a professional to discern. What would be hard though is interrupting the performer during this window and stopping them prior to playing the second note. Errata: Some first notes are longer than a quarter notes. Some tempos are different than 120 BPM. It's possible to notice something before you can effectively communicate it.

  I think they covered this pretty effectively in Whiplash "not quite my tempo" https://www.youtube.com/watch?v=GBvBu5ErSSo https://www.youtube.com/watch?v=GBvBu5ErSSo

    That's a fictional movie. There are a lot of things that are accurate, but it's not really evidence of any real person's ability. Also, Fletcher still takes several notes to hear the incorrect tempo.

      Sometimes, but he deliberately takes his time before hurling his displeasure. And it being fictional doesn't really matter. It's a demonstration of the subject at hand. Nobody claimed it was real using actors to portray a recreation.

  To add to this, before playing musicians usually set themselves up which will also include counting themselves in. I'm sure if you're very experienced with playing with orchestra or chamber (as Uchida and my friend are) then there is a non verbal language they dial into, call it telepathy if you will, that lets them sense that count in. Sounds fictional but dancers and fighters will also attest to being able to read the thoughts of their partners... So the first note may also include 1-2 bars of silent counting
