Winbledon is an interesting example. Surely, if yuo validate on a
validator at a tram-stop somewhere, travel to Wimbledon, change to
District Line and then later touch-out at a tube station gateline, why
would it not be possible for the Oyster software to calculate one tram
journey and one tube journey automatically? I cannot se why you have to
validate at Wimbledon in that case.


Because there is no need to validate on exit from the tram - it's all
done before you board just like a bus. Therefore the card is ready for
the next journey. If you only validated on exit from LU you would be
charged £4 on PAYG as there would be no entry transaction at Wimbledon.
AFAIA there is no through fare from Tramlink to and from LU. Therefore
interchanging passengers must validate in or out from LU and validate
"in" at the Tramlink platform at Wimbledon prior to commencing a
Tramlink trip from there. In this location it is all entirely logical
once you realise there is, in effect, a tramlink paid area inside the
SWT / LUL one.

I realise all this but I still think that it should be possible for the
software to treat an exit on a tube gateline with a card with only a
Tramlink validation as one Tramlink and one tube journey.
