I tried just now to recreate that exchange on AIM and couldn't get it down to the same second. I got 2 second gaps twice and a one-second game once.
But...
Did you type 2 words before pressing enter and then type 4 words before pressing enter again?
Or did you use single words or two words each time?
This is important stuff. Important distinctions. Any recreation has to be similar to the original.
I'm not saying Foley isn't guilty, but he's probably not guilty guilty.
