Last time I used the NLL I didn't notice trains queuing up on the tracks.
More like people queueing up waiting for anything to show up so I can't
see how a train once every 10 or 15 minutes or so crossing a few other
tracks would cause much if any conflict.

Trains in both directions need to cross each track, so it's 8
timetable slots per hour on each track, and you the gap on each NLL
tracks has to occur at the same moment to let the ELL train cross. NLL
peak frequency will son be 8 trains per hour in each direction, and I
believe freight slots will still be required during peak hours. So
that's a massive timetabling and reliability nightmare. Not
impossible, but the alternative it had to compete against (and the one
they chose) was an ELL that's completely segregated at its northern
end, which is going to make it and the NLL much more reliable.

(and I can't see it could have been made cross-platform at Finsbury
Park, at least not in both directions)

Surely better than the inevitable sardine
situation thats going to happen on the Moorgate and Victoria lines once the
northern ELLX opens.

I think you're overestimating its appeal.
