But there's apparently different rules for offpeak returns and offpeak
*day* returns. That needs more colours.

Or they could implement saner restrictions.

But that's the point of wanting the colours - it shows whether the
restrictions are sane or not, in particular highlighting the edge cases
where one ticket is valid but the next cheaper one isn't.

Presumably in this case there's one train that they want to send the
first wave of cheap ticket people off to London on, and the following
train the next wave. Maybe it would be overcrowded otherwise (and who is
to say they'd merge the two waves onto the first rather than the second
train, if the same threshold applied to both?).
