In regards to, "We realised the mistake on the morning of the keynote (November 3rd) and at that point it was too late to change it." Confused. While can understand not being able to change a number in a presentation last minute, the person reading/presenting could certainly just mention on that slide, or that number is actually x. Mistakes happen, but since they realized it before presenting why wouldn't they mention that rather than providing the knowingly wrong info?
