In essence, they've been fiddling around with the destination displays. Again.

This time it seems to be to make the route-varying letter smaller (see here: https://flic.kr/p/2kw3c9k). I've seen a couple of other photos this evening of a couple of 1As of which both had the smaller number so they must be seriously considering rolling this out.

What's the theory behind this one? Is there a small glimmer of evidence that suggests that passengers may find it easier to read the *full* route number when displayed in this way?

It's those important things again. 
Of all the things they could do to make 'things' better, such as improving links, timings or whatever else that would benefit customers - they're spending time fulfilling self indulgence needs and titivating things that didn't need titivating.
Must have ran out of paint this week... Or Stennings emails have been down.
