Autotimers and Description Uniqueness

[ccs]

Please explain what situation when setting up autotimers using descriptions would require you to realise that series one is described as 1960s and series two as 1970s.

The 1960's or 1970's is irrelevent, I've already acknowledged more than once that I was wrong to comment on them.
I thought the descriptions were wrong, I didn't double check, hence my reference to "type of knowledge you might expect to need".

The two series are clearly identified, that's what I normally check for first, the decade just got in the way.
