Which "waiting list" are you referring to? Please post the link.
That it represents 50% is a huge assumption.
I cannot work out the time period you are referring to.
More people have their case on Trackitt than ever participate in the discussions.
These
posts shows how many unapproved cases remain just from those cases added to Trackitt since October 2011. I have every name associated with those numbers.
Even allowing for a large number not updating and recent additions, the number is going to be substantially more than 140, even just for 2007 PDs.
Allowing for already approved cases, 140 to be updated would represent a 50% update rate on 2007 PD cases added since October 2011 and excluding any cases added in August. I can well believe that less than the historic 80% are updating their cases, but that is still a stretch IMHO. If it were true, then c. 6k 2007 PD cases have already been approved in August.
