That graph is very interesting,

The captain of the Victor tanker which had a mid-air collision with a Buccaneer over the North Sea in March 1975 was plucked unconscious from the sea by the crew of a fishing boat, before being transferred to an SAR helicopter. He was in an immersion suit (but not in his dinghy) and wasn't wearing his bunny suit, which were uncomfortably warm in the Victor. I can't remember the figures, but I know when his temperature was first taken it was so low that the medics were amazed he was still alive. This after less than two hours in the water in an immersion suit. I'm assuming North Sea temperature in March aren't much different from the North Atlantic.
I remember we all started to wear bunny suits under our immersion suits after that.
Blimey
Fox, I was getting twitchy half a mile out over St Ives bay in a C152 in the summer! Respect
