How long between episodes (TV time)?

On average how much time do you think expires in the 'Seinfeld' universe between weekly episodes? This week Elaine said it had been 3 weeks since she spoke to Puddy. From episodal evidence and conjecture, what do you think the average interval is?

What's real cool is that it really had been 3 weeks since we've seen a new episode w/ David Puddy. 2 weeks ago was a repeat, last week was The Cartoon (No Puddy) and last nights The Strong Box had no Puddy either. And remember in The Serenity Now, Elaine says to Jerry "...You break up with a girl every week" and most of the time, he does break up with a girl every week.
