'Just all' or 'all all'?

Anybody know if when BBC open submission shows say that all sketches are read does that mean:

'just all' - they start reading every entry, but stop partway if they don't like it;
or
'all all' - each entire sketches is read.

Obviously you want to hit the mark from the start and continue delivering solid laughs all the way through, but allowing for allowing for differences in sense of humour that may not always be possible. So in that case is there any benefit to having what the producers find funny at the start of the sketch (i.e. Just all) , or doesn't it matter as the entire sketch gets read (all all).

Thanks in advance for any insight on this.

I don't know the answer, but I strongly assume it's 'just all'. Doesn't necessarily mean you need a joke at the start, though, just something original or engaging would probably do.

I think it's sensible to 'front-load' your best sketches, for exactly this reason.

I'm not sure it matters. Even if they force their eyes down the whole page, they have probably decided if it's a possible pretty quickly from the first few lines. Or at least decided to ignore "impossibles" eg all the Jimmy Saville based sketches they must get from "edgy" writers.
