I did guess one number, I even waited over 5 minutes each time, but when you post twice in a row it adds a line under and shows the time you modified your post. Then i did a third one and it extended the modified time.
Notice the 50 minute gap from my first (with the three numbers) and your post, I did 3 numbers in that time. (Well 3 numbers in a 16 minute gap)
