I confess I did not think of the existence of correlations. I simply  
thought 1.2% was quite low,
wondered how that could be, and marvelled at how close this simple  
calculation came to
that result. My feathers may deserve some ruffling - but I remain  
obstinately mellow! Anyway,
fwiw, it was my 1.232% of survivors that I thought was on the high  
side. I should read the paper.
