I'm solo mining, and my reward frequency has dropped a lot in the last couple of weeks.
Last blocks were found on November 1st, 6th, and 15.

Given I have 8 threads mining at about 1.1 khash/sec ~ 9 khash, I should find a block every

2^32 * .64 / 9,000 seconds =
305,000 seconds =
3.5 days

Given the above calculation, how likely is 14 days without a block?

I would say (1-1/(0.64*2^32))^(9000*86400*14), or about 2%. Not very improbable.

Quite improbable in my book. I'm mining using the old "optimized" miner that was released with Litecoin, and the latest Litecoin client (the one that enforces a minimum transaction fee). I wonder if there's something wrong with the setup. It's possible I haven't mined a block since upgrading the Litecoin client.

Same as bitcoin, difficulty 1 = about 2**32 hashes average per block.

Odd.

Alright, thanks. I was reading that from the bitcoin wiki and I didn't know if Litecoin used the same formula.

It seemed unlikely given the disparity (Bitcoin's difficulty is what... 1.1 million?), but considering that litcoin is still brand new, is built for CPUs, and has per-computer measurements in khashes instead of Mhashes, that makes sense.

What exactly does the difficulty rating in litecoin translate to?

Right now I'm seeing difficulty 0.64ish, but I couldn't find what that meant in terms of hashes expected to get a block.

Edit: From http://allchains.info/ could I hypothesize that since ~ 19 Mhash/s is being run on litecoin, and that since 28,800 LTC are generated daily, that 1 khash/s translates to ~1.51 LTC/day?

Would that mean that a difficulty of 1 implies approximately 1 LTC/day/khash/s (plus or minus a lot for layered approximations)?
