Where politics meets statistics
Alex Salmond's demeanour was modest, contained and controlled - with the occasional dry quip lobbed in the direction of the wicked media who were questioning him about GERS.
(No, not the outfit who may or may not make it to the cup semi-final to face doughty opponents. We are talking about the Government Expenditure and Revenue Scotland report.)
As Mr Salmond was cheeky enough to note, I have covered every one of these events down the decades.
I recall their genesis as part of an effort by the then Conservative Secretary of State to prove the worth of the UK to Scotland. I recall the intriguing occasion when the Chief Economist, a civil servant, said that the figures, in themselves, said nothing about prospects under independence.
And so I am aware that this publication is, in essence, a political event as well as a statistical one. It has been from the outset and is so now. It is about competitive interpretation rather than a simple sum.

Scottish independence: Brown outlines 'more powers' offer
We learned rather a lot today from Gordon Brown. We learned that he can still deliver a detailed, thoughtful speech ad lib while striding back and forward across the platform, restless like a caged but powerful lion.
We learned what I suspect will be the framework of the Labour offer on more powers for Holyrood when the party's commission reports next week, prior to conference.
Scottish independence: Gordon Brown outlines 'power-sharing' UK
Mr Brown delivered his speech in a church hall in Glasgow's East End, enabling him to recall a few gags from his days as a son of the Manse in the Dear Green Place.
But his approach was decidedly serious. The UK, he said, required to be effectively recalibrated, shedding the lingering image of solitary centralism.
First ministers questions: government accused on justice reform
There he sat, silent and lugubrious. All around him, his accusers demanded his head - or at least a stiff sentence of community work.
His name? Kenny MacAskill. His designation? Justice secretary. His crime? Steering a piece of Scottish government legislation through a decidedly sceptical chamber.
Scottish independence referendum: All, or something?
It is emphatically not the case that the focus will shift entirely away from the independence offer. But, equally, it is important that the alternative proposals for Scotland's future receive a fair deal of attention - and scrutiny.
Nicola Sturgeon decided to retaliate first - by suggesting that her opponents' ideas, both extant and emerging, fall short of Scotland's requirements.
Scottish independence: Sturgeon says devolution proposals 'fall short'
"It is emphatically not the case that the focus will shift entirely away from the independence offer.
"But, equally, it is important that the alternative proposals for Scotland's future receive a fair deal of attention - and scrutiny.
Scottish independence: Standard strife at Holyrood
A peculiarly acute dilemma confronts Alex Salmond and the Scottish government with regard to the comments from Standard Life.
Mr Salmond tells MSPs and others that he has answers ready to the concerns raised by the Edinburgh finance company relating to the possible consequences of independence.
Scottish independence: Business leaders grilled on the referendum
Holyrood's economy committee this morning took evidence from sundry business folk, each offering their opinion on the constitutional debate.
And will there be a report from this event? There will not. For the very understandable reason that there could not be but a single report. There would be two. At least. Welcome to Scotland in this referendum year.
Scottish independence: Pop and politics at Holyrood
Rather wisely, our leaders are generally leery of mingling too readily with the world inhabited by popular beat combos.
Pop and politics, experience teaches them, do not always mix.
