If I wasn't clear i was not talking about the number of EV that you could get detail on I was talking about taking a shot that gets detail for that range AND THEN overexposing by another 8 stops - true over exposure - not a great idea. Hence my comments on film overexposed by 8 stops is fine (not really)

We are talking about exposure latitude towards overexposure. The example I posted was overexposed by 6 stops, true overexposure. The example I saw at Kodak was overexposed by 12 stops, true overexposure. Eventually the highlights will roll off and ruin highlight separation, which happens sooner with some films than others, but 6-12 stops true overexposure latitude is normal.
