Wrong, yet again GTS. If you did proper research you will notice the walking distance is 50 metres NOT 200 metres !I honestly just don't know where you get your facts from, you have been miles off the mark many times on this particular subject.
Also in the DLA days most assessments where carried out by local GPs, but not the claimants GP ! Those GP assessments were later farmed out to the likes of Capita etc being a much cheaper option with the introduction of PIP.
I'm sure that you don't actually read what people post.
I said that if someone can walk 200 metres or more either aided or unaided then they will be deemed to not have a mobility issue - thus no points would be awarded.
Why bring 50 metres into the equation? At best being able to walk no more than 50 metres would get you standard mobility. Being able to walk over 50 metres would not get you any award. You would only get the Enhanced if you cannot walk more than 20 metres.
I'm sorry you are wrong. The doctors that used to assess for DLA were under contract to the DWP by Medical Services. They may well have been GP's but in the main they were retired from general practice.
Price and value never came into it. Simply because very few DLA assessments actually took place. I claimed DLA in 1995 and had various reviews until I was assessed for PIP in late 2013. All of my DLA awards were the result of what was on the claim forms and a report from my GP when requested by the DWP. I never had an assessment.
The cost of assessments for PIP is far more than the assessments for DLA.
The real reasons for bringing out PIP was (a) to make it so difficult to qualify when compared to DLA, thus with the intention of cutting what was being paid out under DLA to claimants by at least 20% and (b) continual re-assessment in the hope that the DWP had more chances of cherry picking to reduce or eliminate the previous PIP awards.
