Export/Import-SPWeb and -IncludeVersions

I'm exporting and importing an spweb into a new spsite.

Many of the documents have over a hundred versions dating back years.

I want to limit the number of versions to, say, 10, but don't know what that means in terms of major and minor. I readhttps://technet.microsoft.com/en-us/library/ff607895.aspx, but still a little unclear of the syntax.

EG: Export-SPWeb ... -IncludeVersions 10... Would this export only the last 10 major versions of a document? Or last 10 major and minor versions?

Thanks,

Scott
