I've now got a 1.6 diesel Bravo which at a steady 50 or 60 will be doing 
70-80 mpg

Yep.
On paper it's a smidge more economical than my Bravo but only having a five 
speed gearbox instead of six makes me think that in practice it won't be any 
better.
My average from new is a genuine 56mpg but on the last couple of full tanks 
I've got over 60 which is very good.
My Octy would typically do about 50-52 on a tank depending on how I'd driven 
which was still pretty impressive for a car that would also do a 9 second 
0-60 (though obviously not returning 52mpg at the time)

At a constant speed the instananeous figure would be at that level though it 
would be tricker to get that as long term average.

I run LPG and at around half the cost of petrol or diesel per litre I reckon 
that I am getting high 70's low 80's equivalent � for �.  Might not get as 
many miles per gallon but it is miles per � I am more concerned with.  I 
average over 150 miles per �10 currently saving about �400 per 10k miles on 
fuel alone and �15 road tax helps too.
