So if your pressure group HS2ActionAlliance use Dft financial and environmental figures (and accepts them as roughly accurate) for their own arguments that makes them as 'water tight as rice paper' too or is it just your own personal bias of who is saying them?

If you actually read it rather than skimmed it you would find they used the raw data on local authority population from the Census, PLANET Long Distance model for travel demand, Treasury growth figures and National Passenger Survey for calibrating business trips per pound spent for each industrial sector, but threw out the Dft methodology as too simplistic (for instance grouping of 8 local authorities in London and grouping 4 in Manchester loses the fine grain of travel patterns within those cities) instead using their own finer grain analyis. As KPMG also say in the report:

As KPMG also say in the report:
We have developed a practical and transparent methodology to quantify the economic impact of investment in HS2. Our approach makes use of data and assumptions assembled to support the August 2012 economic case for HS2.
This approach builds on KPMG’s previous work in this area, considering the relationship between transport connectivity and economic output, but undertaking a more fine-grained analysis of how additional economic output is redistributed, on the basis of production cost advantages arising from economies of agglomeration together with transport cost advantages.
