But the Ibrox midfielder predicted he can scale those heights again soon - when he has fully recovered from a niggling groin injury.
Law got his career at the Glasgow giants up and running in some style at the beginning of the 2013/14 campaign.
The former Motherwell player netted a first-half double on his competitive debut against Albion Rovers in the Ramsdens Cup in July.
And the Englishman quickly followed that up with strikes against Brechin City and Airdrie when SPFL League One got underway.
His general play in the centre of the park, too, was highly impressive and he quickly won over the Light Blues support.
Since then, though, Law readily admits that his performance levels have dropped.
But playing on through an injury was largely responsible for that slump and he is optimistic that better times lie ahead in the second half of the season.
"I went through a spell this season where I had a little dip in form," he said. "I had been carrying a niggling injury for a month.
"Looking back, I maybe should have come out of the team and had a rest. I didn't really do myself any favours by carrying on.
"I have been pleased to get myself back out there injury-free for the first time in a couple of months and get back into the goals.
"Scoring two goals against Stenhousemuir did a lot for my confidence levels. I was delighted with that. I got one in the win against Dunfermline as well."
But, Law added: "I am still trying to get back to where I was before I picked up my injury. It isn't always easy to do that.
"We haven't managed to train a lot recently with all the games that we have had. We have had plenty of games, but not training.
"I am trying to work my way back to where I was, to get my fitness back to a good level. But because we haven't been able to train you lose bits and pieces. I am still getting back to it.
"Hopefully the games I have been involved in and the goals I have scored will help to take me on a little run again.
"I certainly want to keep scoring goals and keep helping the team to win games in all of the competitions that we are involved in this season."
Despite his harsh self- evaluation of his contribution in recent weeks, Law has still managed to amass his highest tally of goals in a single season.
The 25-year-old has netted no fewer than nine times for Ally McCoist's side since arriving on a free transfer during the summer.
Only Jon Daly, who has 18 to his name, and Lee McCulloch, who has 12 thanks to being the designated penalty-taker, have been on target more often.
Law managed to reach his best-ever mark with a strike that he rates as the sweetest of his career to date against Stenhousemuir earlier this month.
Having given his team the lead in the first half, he rifled a volley into the top corner from an acute angle in injury-time at Ochilview.
He said: "This is the most goals I have scored in a season. I have got nine and the most I have scored before that was seven or eight when I was with Motherwell.
"I really, really enjoyed the last goal I scored. I managed to catch it perfectly and it went into the opposite top corner.
"If I do say so myself, it was a good goal, very possibly the best goal I have scored for Rangers so far."
LAW got preparations for the League One meeting with Forfar Athletic at Station Park - a venue Rangers have struggled badly at this season - under way today.
Despite his side's 17-point lead at the top of the third-tier table, he is determined for them to maintain their unbeaten record in the league.
And he is also keen to add to his haul of goals, and help those around him to plunder their fair share, between now and the end of the campaign.
"To reach my highest number of goals so early in a season has been great," he said. "But I will be looking to keep going and match what I have scored so far in the second half of the season.
"I certainly want to get into double figures. If I can get that it will be great. I also want to keep chipping in with assists as well.
"I have always managed to do that throughout my career. Basically, I just want to help my team out whichever way I can.
"I was delighted to get two goals and have an impact on the game against Stenhousemuir. But I am always just happy when I can help the team out.
"The most important thing is that we keep winning games. Fortunately, we are doing that at the minute. Hopefully, that will continue between now and the end of the season."
