It was nonsense Steve in that you'd singularly failed to look-up or
at least mention the cheap Advance rail fares (which will have been
available for weeks and weeks now, they haven't just been released)
and instead just quoted the fully flexible GBP 202.70 fare.

I quoted the only fare that National Rail quoted to me. They didn't
offer any advance purchase or any other fare at all.

Yes they did. I've just checked Wednesday April 27th on National Rail:
