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."
Before Will Greenwood started breaking down moves off the field, he was doing the business on it - and no match better illustrated the type of marauding centre he was than in a virtuoso performance against Wales.
