MG, I'll agree that Constable Chaos' picture is probably a more realistic picture of deployment effectiveness for those dynamic tasks, (10 minute time to lift!!??) however as with all things, they need to be looked at with open eyes from both sides.
Your pic gives the impression Wales is left bare, with the figure of 3,063,456 placed in an area of no coverage. In reality this picture below shows that the areas you show with no 'effective' cover in Wales, as it happens all the areas in blue, have a very sparse population.

Taking the other figures that are on the Constable Chaos picture into account, covering the 'effectively uncovered' parts of England, they total 2,889,000. As the population of England is just over 53 million, that 'uncovered' figure represents about 5% of the population. Not that bad really if you think about it, especially when Constable Chaos has reduced the NPAS circles by 60% to support his/her argument.
Just saying
