Comment (by azaozz):

 Yeah, the comment is not that accurate :) From the code, the intention is
 to reduce the chance for a check when the number of sites increases. It
 tries to keep (very roughly) the number of checks whitin the same range
 regardless of the number of sites. It might be a bit more readable like
 this:

 {{{
 if ( $c <= 50 || rand( 1, ceil( $c / 50 ) ) === 2 )
 }}}

 This can be a bit more "sensitive". A 5% chance for a network whit 1000
 sites (1% for 5000 sites) seems quite high compared to a single site.
 Perhaps the magic number should be 30 or even 20, not 50.
