Alex,
Does the C.O.D. of the 'larger people' on the list correlate directly to a CO2 hit?
Could it be that the this group may be more prone to Heart failure or some other non Rebreather C.O.D.?
It would seem that if the metabolism rates are as high as suggested that there would be a lot more incidents.
Empirically divers are getting three to four hours out of their EAC's, on a regular basis, without incident, many of them 'larger divers.'

Large divers suffer all round. More on CO2 hits, more on hypoxia hits (less time to respond I guess), more on heart attacks.
The warm water factor, and that deco is the lowest RMV so the best dwell time, means that people are getting more time. However, it is not the way to plan a dive. Better to look at your metabolism, look at the capacity of the scrubber, then when you have used 2/3 *1.2 times that much O2, get out.
I emphasise this is nothing specific to EACs, it applies to all scrubbers. Indicators are people are pushing them, so when the muck hits the fan there is not a lot of slack about to accommodate things. We should think in thirds, just like trimix gas management. Get out with a third left, even though trimix costs more than EACs or granules.
