Of course G III kept a diary. It's just that no- one in the States bothered to phone him up that day to let him know what was going down :-} That's part of my point - the technology wasn't there. For them, it was unfortunate.
But not using technolology when it's available - well, in America, we call that "dumb and dumber" <s>
Many Brits (and other countries) balked at the notion of using technology (e.g. Hawk-eye system) for line calls during tennis matches - well, the system (while not perfect) has been an improvement.
