Number of ESA functional assessors in the country.

Hi,
Does anyone have a rough idea how many WCA assessors there are nationwide?
I'm trying to get a very rough figure on how many deaths or suicides each assessor statistically causes per year so that I can challenge the NMC about their tacit approval of their members working for Maximus.
Maximus state that they have 150 assessment centres.
There's an old figure that the WCA caused 590 suicides between 2010 and 2013, so 200 a year (ish).
So just 1 and 1/3 suicides per year per assessment centre.
If each centre employed six assessors (mad guess) then each assessor, statistically, would drive one person to suicide in just under 5 years.
That would be the amount of blood each assessor would have on their hands.
However, I don't know if all centres are a similar size, or if the big city ones employ more than six (anyone got an idea how many Manchester will employ?)
The other statistic I find is more recent that 80 claimants a month die after being found fit for work.
This is more significant and means that each centre is responsible for around 8 deaths a year.
If my guess of six assessors at a big city centre is true (probably not, though) then each assessor's actions lead to more than one death per year.
I'm doing a lot of guestimating here with my figures, and I'm pretending that they are all nurses for the sake of my complaint to the NMC.
I'm guessing at the mo, though, that each nurse/assessor causes one death by suicide every five years and more than one death every year for all causes.
They do this by ignoring the NMC code and by knowingly discriminating against ill people, particularly the mentally ill.
As well as the suicides, and other deaths of course, each nurse bears responsibility for their share of the thousands of people left mentally scarred by the experience, and the hundreds of thousands scared witless at the thought of an assessment.
I want to impress upon the NMC the scale of their member's murderous actions, and possibly even point it out to my next assessor.
They seem to think they're being good little girl guides by implementing the WCA, and ignore the destruction they cause
I'd like them, and the NMC to realise what their job actually is.
ie, a government thug.
Cheers.
