The Swan Yamaha rider grabbed pole position up in Scotland in 2011, and then stormed to a double race win, both of them by over five seconds.
Up until now, this season has not seen the same level of dominance from the 27-year-old who finds himself second in the standings, a solitary point behind Josh Brookes.
But, with almost a month having passed since round four at Snetterton finished, Hill admits that it is hard to predict how round five will play out.
“Of course I go into Knockhill with a lot of confidence,” said Hill. “Our results there last year were fantastic and we blew away the field so hopefully we can repeat that this time around.
“But compared to last year there have been a lot of changes made to the rules, everything is a lot closer in terms of electrics so it won’t be that easy.
“On top of that it has been a while since we were all together so we haven’t worked as much on the team as we would have liked in this month off.
“Some of the team have been at the North West and the TT this past month but we’re back now and will be working hard to make sure we’re back at our best before Knockhill.”
Last time out at Snetterton, Hill was in with a shout of the first double race win of the season after topping the podium in race one.
But, after engine trouble forced him out of contention in race two, Hill admits he is itching to get back to winning ways.
“What we want at the moment is to be winning races,” he added. “Snettterton was a real disappointment because I felt good and a problem with the bike denied us points.
“So Josh [Brookes] is on top of the standings at the moment but we will be doing everything we can to make sure we are back in front by the end of this round.”
