Similarly, Scottish First Minister Alex Salmond has partly made the case for a "Yes" vote being about ridding Scotland of Conservative government.
And his deputy, Nicola Sturgeon, has accused PM David Cameron of "struggling to locate that part of his anatomy" which would see him go head-to-head with Mr Salmond in a TV debate. (Ms Sturgeon's advisers assured me at the time she was referring to the prime ministers "guts". Or lack of)
Claim and counterclaim
Scotland's economic health has been a hot topic in the campaign
How much better off will people in Scotland be? Will public services be better or worse? What does Scotland need to be an international player?
These are all questions the two sides have sought to answer with a dazzling array of figures.
And not content with punting their own views, the two sides resorted to attacking each other for dodgy sums.
Mr Salmond said the Treasury's calculations had been "blown to smithereens" because they'd already been caught cooking the books, while Chief Secretary to the Treasury Danny Alexander accused SNP ministers of offering voters a "bogus bonus" because their version hadn't taken all the factors into account.
Expect plenty more stats chat in the weeks ahead, as the campaigns continue to seek to put forward their economic arguments.
The prospect of a stronger Scotland within the UK has formed a key part of their argument, but the SNP government has questioned their ability to deliver and says the nation needs real independence.
'Mibbes Aye, Mibbes Naw'
Both sides of the campaign have been going after undecided voters
If you are an undecided voter, the campaign machines are coming your way.
Those who have yet to decide whether their "X" is going beside "Yes" or "No" are hugely influential because they're open to persuasion - and polling data for the last few months indicates "don't knows" make up anywhere between 12% and 29% of the electorate.
Supporters of the Union have also looked to history.
During a time which has seen big world war commemoration events, David Cameron used a conference speech to pay tribute to a Scottish ancestor, Captain John Geddes who died in battle in 1915, but showed "extraordinary heroism" in representing Britain standing together "when the chips were down".
And what might the two sides of the campaign make of the 2014 Commonwealth Games, being held this summer in Glasgow?
It is one of those international events in which Scotland competes in its own right.
But if you're heading to any sporting events in Glasgow between the end of July and the start of August, expect to at least see a few Yes Scotland and Better Together flyers.
Barack Obama made an unexpected intervention in the debate over Scotland's future
As one-time US defence secretary Donald Rumsfeld once noted: "There are known knowns, there are things that we know that we know. We also know there are known unknowns, that is to say we know there are some things we do not know.
"But there are also unknown unknowns, the ones we don't know we don't know."
The referendum campaigns may well be planning every last second of their strategies, but not knowing who might be next to put their head above the parapet will keep them on their toes right up until polling day.
It was another day to remember for Scotland at the Commonwealth Games, with Dan Keatings winning gold on the pommel horse, Eilidh Child winning silver in the 400m hurdles, Daniel Purvis winning bronze in the gymnastics rings and wrestler Alex Gladkov also earning bronze.
Tomorrow, Scotland are guaranteed two medals in the lawn bowls. The Men's Fours and Darren Burnett in the singles will be hoping to add two more golds to Scotland's collection.
Four of Scotland's boxers, who will all win at least a bronze medal, are also in action.
Join us again at 07:00 tomorrow when we will bring you all the latest news, sport, weather and travel and of course the latest on the Games. You can hear all the latest news at Radio Scotland and on the website. Good night.
Team Scotland are getting excited. With 43 medals now in the bag, and another six guaranteed in the boxing and lawn bowls, they tweeted:

There will be some good spells of brightness or sunshine too outside of the wet weather. Given the random nature of these showers not everyone will see them.
Temperatures should reach a high of around 18C - 19C through the central belt and Grampian. A couple of degrees lower elsewhere.

In Glasgow all roads used in the cycling time trial are now open again with restrictions lifted.
Tonight's athletics at Hampden means that drivers are urged to avoid the stadium and surrounding areas.

Child did a lap of honour at Hampden Park after winning the silver. The crowd cheered her on and sang The Proclaimers hit I'm Gonna Be (500 miles).
Scotland have now won 43 medals at the Commonwealth Games.
Louise Martin CBE, Chair of sportscotland, said: "To move onto 43 medals is another fantastic milestone for Team Scotland, and with three more days of competition still to come I can't wait to see how many more we can add to the tally.
"Daniel Keatings produced a faultless routine on the pommel horse to take gold, while Eilidh Child performed magnificently in front of a vocal home crowd at Hampden to take silver in the 400 metres hurdles.
"The bronze medals from Daniel Purvis on the rings and wrestler Alex Gladkov meant it was four medals for Team Scotland on another successful day at the Games."
Eilidh Child has finished second and won the silver medal in the 400m hurdles at Glasgow 2014. The winner was the Jamaican Kaliese Spencer.
It's half-time at the Anoeta Stadium in Spain with Aberdeen drawing 0-0 with Real Sociedad.
Real, as expected, have had most of the ball and the chances, but Jamie Langfield has yet to be forced into a meaningful save.
In the other tie, St Johnstone trail FC Spartak Trnava 1-0 at McDiarmid Park. Ivan Schranz grabbed the goal in the 33rd minute.
It is nearly time for Eilidh Child's race in the Women's 400m hurdles.
As well as the Commonwealth Games, it's another big night for Scottish football.
Both Aberdeen and St Johnstone are in action in the 2nd qualifying round of the Europa League with the Dons taking on Real Sociedad in Spain while the Saints entertain Spartak Trnava at McDiarmid Park.
McInnes feels that having faced four competitive fixtures already in Europe, the Dons have an advantage with the Spaniards only having played a number of friendly matches.
"We want to do as best we can," he said. "We feel we as a team are in a good place just now and take the confidence from the start we have had to our season."
Daniel Purvis has won the bronze medal in the gymnastics rings final.

Anthony Davis, a 62-year-old Jamaican who is one of the leading sports administrators from the Caribbean island, wants to create a link between Jamaica and Scotland that could see Scottish sprinters train with the best in the world.
Davis, who competed at the 1980 Olympics, is a student in Glasgow and has studied how Scots organise athletics events.
He has held initial talks with athletics bodies to create a programme where Scottish sprinters would train in Jamaica while Jamaican officials would come over to Scotland to learn more.

Surely the hardest task is getting through the door.
Perhaps you feel you're too old, not fit enough, or don't have the required experience?
Kevin Moran and Alex Clark have failed to reach the squash mixed doubles quarter finals after going out to Pilley and Brown of Australia.
Scotland's Dan Keatings comes agonisingly close to a gymnastics medal, finishing fourth in the men's floor final. He was 0.023 points away from a bronze.

Team Wales has sent an email to its athletes about their behaviour for the rest of the Commonwealth Games, BBC Wales has learned.
The message, signed by Chef de Mission Brian Davies, tells them it would be "disrespectful" if anyone "were to let themselves, their team-mates and their families down by misbehaving in any way during their time here in Glasgow".
The move follows the arrest of an Australian weightlifter, following an alleged assault on Welsh weightlifter Gareth Evans.
