He told AFL.com.au it could be as simple as straightening his approach.
Jenkins has had more shots for goal this season (33) than North Melbourne's Drew Petrie (27), Geelong's Tom Hawkins (30) and cross-town rival Jay Schulz (29), but his conversion rate of just over 51 per cent has hurt.
Since Taylor Walker's season-ending injury promoted Jenkins to the club's main attacking target, he's returned 11.13.
"Last year I was pretty accurate at both SANFL and AFL level and this year, it's just a little bit of a technical thing that I've identified," Jenkins said.
"I'm just a bit off with my line. I've watched some footage from behind the goals and the way I'm running in's just not quite straight – I'm kicking it pretty much where I'm running.
"I think I've missed 13 set shots this year and 11 of them have been to the right, so that stands out a fair bit."
While frustrating to be leaving so many goals "on the table", Jenkins said he was pleased just to be getting the chances to kick them.
He insisted the technical concern with his goal kicking was easily fixed; the main issue was getting his hands on the ball.
"I've had two games of 2.4 and I'vehad a 2.3 and a 3.3, so if I can turn some of those into fours and fives then it'd be a whole different story," he said.
"If I was spraying them right, left and everywhere I'd be a bit more worried.
"The main thing for me is that I'm getting the opportunity and shots on goal."
Adelaide's next two opponents in Fremantle and the Sydney Swans means Jenkins will line up against two of the competition's elite defenders.
He's got 2012 All Australian Luke McPharlin on Saturday and could face-off against another All Australian in Ted Richards next weekend.
The 24-year-old has the rarest of athletic abilities for a man of almost 200cm but he admitted the next fortnight would prove his biggest test as an AFL player.
"I'm starting to play on some pretty good defenders and I've probably got a few All Australians in the next couple of weeks, so I'm taking plenty of confidence into each match," he said.
"I feel that if I get my fair share of it I'll be able to have an impact.
"I've got some attributes that I'll back in and try and take the game and those guys on.
"It's going to be the ultimate measure of where I'm really at."
