Scotland number eight Dave Callam admits Edinburgh need to cut out the number of errors they are making if they want to challenge for honours next season.
Andy Robinson's side have made plenty of progress this season but are still too far from the top of the league for the liking of Callam - despite being a young squad with an average age of just 26.
The back-rower, who was given a huge vote of confidence by Scotland coach Frank Hadden when he started the 2008 RBS 6 Nations, concedes his form could have been better since that tournament.
A shoulder injury restricted the 25-year-old's game-time in the latter stages of the RBS 6 Nations and he has struggled to recapture his best since February.
Callam said: "I still feel I'm not playing as well as I have done in the past. To be honest, it has been a disappointing year for me. I've not played as well as I can and it hasn't been as good as I would have hoped. But hopefully I can turn that around next year.
"It is the first time I've had a serious injury, but it is all about learning from about and trying to improve as a player.
"We knew what we were doing wrong as a team and there was definite frustration because we were highlighting problems, but then making the same mistakes.
"But the guys have put in a lot of hard work over the course of the season and it is nice when it comes off.
"It is a young team and everyone is learning every week. The frustrating thing is when you make the same mistake twice. But with it being a young side we can turn things around quickly. It is all about becoming more consistent over the next few seasons."
As head coach Stuart Lancaster polishes the axe he will soon wield over his World Cup training squad, Exeter Chiefs coach Rob Baxter has backed Jack Nowell, Henry Slade and Luke Cowan-Dickie to be given a stay of execution.
Italy Under-20s held off a late Samoa blitz to retain their place in the World Rugby U20 Championship on Saturday and head coach Alessandro Troncon believes the experience will have served as a valuable lesson for his young troops.
