Accuracy is the whole point of the site, so corrections matter to us. If you think a figure is wrong, send it over with a source where you can. We check every reported error against the free demo or Amusnet's own material before we change a word, and we won't quietly swap a number just because someone asked.
When we do correct something meaningful, we update the page and its date so you can see it's current. How we verify claims in the first place is spelled out on our methodology page. If we got it wrong, we fix it, and we thank you for the heads-up.
