Geoff,
There is quite a long thread on the Templot forum which considers all the angles:

Don’t worry if you’re not into Templot, the thread is quite unrelated to the Templot software.
I haven’t used these standards myself, but the principle seems sound. I would be concerned with a check span of 16.4mm and back to back of 16.5mm, which leaves only 0.1mm tolerance for track building and wheel erection. Your plan to use a slightly larger back to back feels like a good idea..
Still waiting to hear from someone who has actually built a layout to what Martin Wynne calls EM-SF….

PS I also returned to EM after many years working to P4. Never regretted it.
