Might be helpful. Substitute ‘harp’ for ‘piano’. I have to work at not stopping for or being distracted by mistakes. Need to practice playing thru them. It’s not math.
If you play something like Juke in front of an audience full of harp player, I bet that those errors get noticed.
In a real band scenario, original songs + improvisation, I bet that no one (not even musicians) can spot an error unless it is a very very obvious one.
