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.
Derek Low, 34, from Glasgow, was caught with £191,190 in cash and 78 knotted bags of cannabis, worth about £4,600, at his home in May 2013.
He later admitted being concerned in the supply of drugs and was jailed for four-and-a-half years.
Chris, Bonnyrigg: It's really just simple economics versus nationalism: vote Yes if you're a taker, and Vote No if you're a contributor.
Richie Boy, Dumbarton: So, John Swinney says Scotland won't pay our share of debt. Surely this will have a huge effect on our credit rating and therefore we will pay a higher loan rate if we are able to borrow at all?. After all, if I defaulted on a debt I know I'd be lucky to get credit! Apologies if I've misunderstood the situation.
Mr Brown was appearing alongside Alistair Darling, the head of the pro-UK Better Together campaign, at the event in the Caird Hall in Dundee.
The CBI in Scotland has been warned that a dinner in Glasgow featuring the Prime Minister will be scrutinised in case it breaks the rules on expenditure during the referendum.
The Electoral Commission has ruled Thursday's dinner does constitute campaigning because the Prime Minister is expected to defend the Union.
But it has been assured the cost will be less than £10,000, meaning the CBI does not require to register as a formal campaigner.
The commission, which received a complaint from the pro-independence Business for Scotland group, says it will monitor the event.
TJ, Glasgow: If Scotland becomes independent there will be an exodus of businesses and families who are able to move south. The Nationalists have already damaged Scotland and its only going to get worse under independence.
Tom More, Airdrie: I'm completely gobsmacked. I just cannot believe that two Labour politicians, Gordon Brown and Alistair Darling, can extol the benefit of the UK welfare state with its bedroom tax and welfare reform. Labour colluding with the Tories!
Shetland is on the cusp of a "second oil boom", the deputy first minister has predicted during a visit to the islands.
Scott from Bishopbriggs: I was never a heavy smoker but smoked perhaps 5 a day and perhaps 20 at the weekend. I swapped to an e-cig around 6 weeks ago after much nagging by my wife and have to say that this has been a revelation. I still go outside to use it as I've no idea what damage it could do to others but instead if popping out the pub to smoke every half hour to smoke a ciggie, I perhaps nip out once every hour for a couple if puffs. They should be treated as cigarettes so that we can be weaned off.
Dee: These e-cigs still leave a smell on people and, as a non-smoker, I find it disgusting and disrespectful to me.
The Scottish independence referendum has raised many questions about issues in our country.
The City watchdog said RBS did not ensure that it gave suitable mortgage advice to customers.
RBS chief executive Ross McEwan said the failings were "unacceptable and should never have happened".
H, Edinburgh: I understand smoking is harmful to health but why keep on about smokers? I hate the smell of alcohol and dislike drunk people but alcohol is advertised and allowed almost everywhere and is just as harmful to health. Let's ban that and cover it up in supermarkets.
Mike, Carlisle: E-cigs are threatening and undoing everyone's progress in kicking the smoking habit. Stop them now.
Very slow traffic where one lane is closed by an accident on M74 Northbound between J6 (Hamilton) and J5. The Raith accident cleared on M9 Southbound between J5 A9/A905 (Cadgers Brae) and J4 A801/A803 (Lathallan).
Des Swan, Isle of Bute: Stopped smoking about 7 yrs ago thru electrix therapy from a clinic in Manchester called Newways & never tempted to smoke again.
Carol, Glasgow: While I am all for people having freedom to make lifestyle choices, imposing those choices on others is at best selfish. There is no 'greater good benefit' from smoking anything and, as such, all smoking should be done in private to avoid the inconsiderate imposition on others.
