This is the code i changed, so the 8 was previously 5
Maybe make it a core feature? If there is enough interest?
Code:
foreach ($memberStats AS $key => $memberStat)
{
$results = $memberStat->getResults(true);
$count = 0;
foreach ($results AS $userId => $value)
{
if ($count == 8)
{
// we have enough for this stat
break;
}
