The two bits in bold seem to be the key. Until details of any agreement between the UK and EU have been reached there can't be an understanding of the future context and environment for the forecasts. And this is equally true of any forecast for an independent Scotland whether in or out of the EU. If Scotland voted for independence, any longer term forecast would need to take into account the separation agreement between Scotland and rUK with regards to any share of UK debts etc. Until this is known the forecasts are pretty much just guesswork or more likely worst case scenarios.
That'll be a long-winded 'I agree' then!
So do I btw!
I'd suggest it was more 'most likely' than 'worst case' that they used - though they could well match!! How such levels of uncertainty are factored into predictions - and documented - depends on the approaches of those that are making the predictions! That's where the predictions of 'independent' bodies like IMF and OBR carry more weight than those of others! That said, the exact numbers are very unlikely to match reality!
