Scotland star Chris Paterson insists the rare occasions when he misses a conversion or a penalty actually make him a better goalkicker.
The former Scotland captain - who forced his way into the Scotland side during the RBS 6 Nations after being left on the bench against Wales and France - failed with a couple of tricky efforts against Connacht on Friday but has no confidence issues as he prepares for this week's match.
Edinburgh face EDF Cup finalists Cardiff as they seek to move further up the Magners League table and And Robinson's side can enter the field safe in the knowledge that Paterson is sure to be on song with his right boot.
"It (missed kick against Connacht) was right at the end of my range and it was quite blustery really. Unfortunately it was just inches short," said the points machine from Gala.
"The key factor for me is evaluating every kick. If I do miss a kick then I know how to put it right next time. With that one, I couldn't have struck it any better - it was bang on line - but it was just a wee bit too far."
Henry Slade admits he could not watch his England team-mates celebrate their RBS 6 Nations Grand Slam triumph after suffering injury heartbreak, but now has the Red Rose's summer tour to Australia in his sights.
