I wouldn't bother. They can come here if they're really interested. And if they're not, there's no point in going there. I suspect they've made up their minds and are now looking for evidence for their MUS FND nonsense to further their careers. If you go you'll most likely be shoe-horned into whatever narrative of the moment they feel like assigning to you - vexatious for asking about PACE, criminal for throwing a coffee cup, asked to leave for "harrassment" as
@dave30th was, etc etc.
The only people who have a limited understanding of how best to support patients with CFS/ME are those who've had their fingers in their ears for the last 30 years. The information is out there, listen to the sufferers or talk to the real experts, you don't need to fund a new "study".
There isn't really any conflicting advice, there's what sufferers and real experts have taught themselves over the years, and there's the noise from the discredited PACE trial. Let's not pretend that there's still a debate here.
Cancelling the study and taking your fingers out of your ears would be much more helpful.
I would have no part in validating this crap with my attendance, even if I could go.
Interviews, group discussions, let me guess, questionnaires too?
