I have not carried out a feasibility study for what I propose, I just think
it wold be an approach/direction worth considering when making decisions

Rigorous benchmarking etc etc is done in industry, and I accept that open
community may not have the organisation and resources in place to do so, but
start with considering the approach. Open a page, where people can structure
their thinking

Henry has already come up with some thoughts which I read very fast but
sound good

 I would start from encouraging a team of people on this list who agree that
such measures would be beneficial, certainly those who have contributed to
this particular discussion, to brainstorm around how to go about actually
trying out these ideas before implementing either

I presume there is some good social capital on this list. Probably there are
people beyond this list who could contribute time and expertise/

all the professors, the doctors, the consortia?

 Once you know who's interested to contribute in terms of time, skills,
maybe some student or departmental time, tools etc, make a plan accordingly.
some element of crowdsourcing within the SW community,f

first making a plan, then breaking down the plan into small tasks that can
be performed with limited effort on a voluntary basis by each etc

even one small measurement is better than none?

Ultimately it looks like its the WG which has to plan for this activity, and
if some knowledge/skills/resources are not available within the WG outsource
them to the wider SW community and beyond

again, I am not trying to sell anything, not sure if the plan I propose here
is feasible (that would not mean that the suggestion cannot be implemented
otherwise) just sharing thoughts

I am sure others can build on them
