Sounds good.

There are two very different conversations there. Both should be  
discuss separately.

1. Self claims and Independent verification by trusted third parties

All Trustmarks have a use case for both self-claims and independent  
verification by trusted third parties. Neither one should be  
dismissed and neither one should be mandated. Why? Well because some  
companies see the benefit of independent verification and some don't.

The importance of independent verification has always been debated  
and to a lesser extent, always will be. Some people will simply never  
see the benefit, no matter how much it is explained to them. With  
about 12 years experience in this field, I spent a lot of my time (as  
everyone else in the same field has done) educating people about risk  
mitigation vs cost of testing.

2. Why we need mobileOK Pro

mobileOK Pro is intended to raise the bar in terms of improving 'how  
mobile friendly' Web sites are in the future.

Web accessibility (WCAG 1.0) has three conformance levels; Single A,  
Double A and Triple A. Single A is easy to achieve. Double A is more  
time consuming and costly to achieve. Triple A is almost technically  
impossible and some guidelines are outdated to the point that  
conformance to them make a site less accessible (I won't bore you  
with the detail).

If every Web site complied with WCAG Single A, the Web overall, would  
be much more accessible to more people than it is today. That would  
be a fantastic achievement so Single A is a great starting point.  
However, Single A is not a high enough standard to strive for. Whilst  
it's a great starting point, all Web site owners should strive for  
Double A in the long run.

Some Web sites will immediately aim for Single A as an easy win and  
stop there, whilst others will immediately strive for Double A. The  
insane and inexperienced will aim for Triple A. The smart ones will  
aim for as many guidelines across the three levels as possible.

I see mobileOK basic as a conformance claim that's slightly higher  
quality than WCAG Single A. I see mobileOK Pro as a claim that's  
slightly higher quality than Double A. Add the additional BPs which  
are not possible to verify without too much ambiguity and you get  
Triple A.

If I'm still not being clear, or anyone would like me to explain  
myself further, I'll happily point to a blog post which I believe  
will explain exactly what I'm trying to articulate here.
