Kaspars Gorkss scored twice for QPR on Saturday but took more pleasure from yet another clean sheet.
Rangers' 3-0 win over Doncaster moved them six point clear at the top of the npower Championship.
Neil Warnock's side have leaked just two goals in the league this term - in a 2-2 draw at Derby - and have not conceded in seven of their eight games.
"The clean sheet record is unbelievable," said Gorkss. "Of course there's an element of luck involved but we are defending well and long may it continue.
"Scoring goals is like a big bonus for defenders but more importantly we got three points and we remain unbeaten."
