I'm not sure of the avg. weight but it'd be a relatively quick excercise to do it by looking at Rieselprime.org. For 50 k's in each 100k range, I doubt the average is much different than any other 100k range. Even if it was, it wouldn't explain such a deviation. If you want and have time, feel free to post your findings here.
You think exactly like I do. I know what are random events seem like nonrandom because there are so many multidues of possibilities for those events. People frequently associate such random events with miracles, mystic happenings, etc., which is completely bogus.
This is likely just one of those "random" fluctuations from the mean as though you got 7580 heads when flipping a random coin 100 times. If you did 1 million tests of 100 coin flips, you'll most likely get 7580 heads at some point. It'd be easy enough to do the math to figure the odds of this happening but I don't have time right now. For all I know, it could take 1 billion such tests on average.
In the prime number world though, I don't think we have clear proof yet that these things are completely random yet so when apparently nonrandom "clumpings" occur, it makes even the most logical amongst us wonder a little bit.
From my 21month experience in prime searching, I believe this is the most unusual clumping that I have seen. But since I've had 21 months to witness such a thing, it's probably random. (lol)
Edit: I just noticed that Chris found a new prime on port 8000 and guess what: It's k=16001700...that's TEN consecutive new primes in that range. Now I can say that primes are very VERY strange.
