Six Nations prediction

For the third year in a row, I've filled out a Six Nations sweepstake form for a member of my family, who seems to be labouring under the misapprehension that I know something about rugby. To be fair to myself, we did somehow win two years ago, although on the other hand we finished second-bottom for the 2007 World Cup! Anyway, this is what I came up with, mainly just by following the overall championship betting (with the exception of Ireland's two home games) -

Weekend 1 :

England to beat Wales by less than 10
Ireland to beat Italy by 10 or more
France to beat Scotland by 10 or more

Weekend 2 :

England to beat Italy by 10 or more
Wales to beat Scotland by less than 10
Ireland to beat France by less than 10

Weekend 3 :

Wales to beat Italy by 10 or more
England to beat France by less than 10
Ireland to beat Scotland by less than 10

Weekend 4 :

France to beat Italy by 10 or more
Ireland to beat Wales by less than 10
England to beat Scotland by 10 or more

Weekend 5 :

Scotland to beat Italy by less than 10
Ireland to beat England by less than 10
France to beat Wales by 10 or more

It wasn't until I'd finished that I noticed I had Ireland down for another Grand Slam, which doesn't seem quite right somehow, but who knows? The results in Dublin could certainly make or break the season for both England and France. As for Scotland, I always try to err on the side of pessimism to counter the peril of wishful thinking - but afterwards I always wonder...am I being pessimistic enough?
