Mathematically, the chance that +1 candidates are prime is smaller, because they are lerger (+2)

I think it is pure luck that I found so many primes.
Some other people on the list who have found very few primes maybe only report these to the forum and not to twinprimesearch.

The candidates are sieved to such a high limit, that there should be no difference between +1 and -1. They are sieved togeter, so it is also not the case, that one of them has less candidates left.

Congratulations Skligmund! It took a month but now there's a new prime leader. We'll see how long this lasts...there are some other quick movers coming up...Zeppelin for one.

Keep crunching...that record twin is out there somewhere!
