The striker netted four times in the 6-1 rout of Forfar as Rangers extended their stunning start to the campaign.
And Clark, who now has seven goals for the Light Blues, said: "I have never set any targets so there is no point starting now.
"I will just see what I end up with at the end of the season.
"I knew coming here that it was a massive club and I would have to bide my time and do well in training.
"The manager gave me my chance and I feel I am doing well now.
"I would say it is harder to score goals at Rangers. A lot of teams come here and try extra hard to beat us and defend really well."
