Hi Chas,
Thanks for your best wishes for my research. Sorry there is a misunderstanding. I am not smart enough to be a scientist or researcher! Just a retired GP dealing with this awful condition.
My “research” only went so far as to learn that Riluzole did nothing to slow the progression and RCH4 definitely does in my case. My concern is how long the RCH4 charity, who supply it for free, will last as they have no funding.
We all know that MND is a most heterogeneous condition so outcomes will vary a lot. The charity http://www.rch4.com say it is ineffective in 16% of the treated population. However I came on this interesting table from PLM and also see that it has the highest votes on ALS Untangled (our American cousins call it ALS).

To address your point about the ALSFRS-R score. You are absolutely right that it is subjective, but it has been validated as the gold standard for measuring progression in the absence of any biomarker being available. As I posted before, what the actual score is for each patient is not in fact relevant. What matters is the CHANGE IN THE SCORE OVER TIME.
Even if an accurate objective protocol or biomarker were developed tomorrow, it would still be academic as there is no “cure”. All an accurate biomarker would do is enable earlier definite diagnosis. Sadly, that’s little help to us.
