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.
