What does this sentence means? Thanks!
If the Fyre documentary is a guide, Mr McFarland belongs to that group, and then some. </p><p>What does"then some" mean here?

<div>“And then some” is a very common colloquial expression. It just serves to reinforce the previous statement. “And that’s putting it mildly” or “And that’s an understatement” would have the same meaning. It means that Mr McFarland most definitely belongs in that group.</div><div><br></div>
