Ugh.. Hmm.. A bit confused. I think I am missing something. I just watched my LV07 submit 8739 shares to ckpool in 1 minute, and it's been doing that consistently - this is what the pool shows (not the miner). This is a lot more than 18 shares from the example above. However, my hash rate (displayed by both, the pool and the miner) is around 1 TH/s.

Also, where did the number 8190 come from? Maybe it should be 8192 (2^13). But then, why 2^13?

On the other hand, miner itself shows 1 share about every 2-3-4 sec - which is consistent with 18 shares/min.

Here is the fragment of the miner log, which is consistent with about 18 shares per minute while watching it in real time:

₿ (149791716) asic_result: Ver: 2CAD2000 Nonce 6504004D diff 498.6 of 971.
₿ (149792476) asic_result: Ver: 2197C000 Nonce F31C000D diff 1494.4 of 971.
₿ (149792476) stratum_api: tx: {"id": 36816, "method": "mining.submit", "params": ["bc1rqk-bla-bla-bla", "67444bb00004c2b8", "0b1a010000000000", "67cc3f06", "f31c000d", "0197c000"]}
₿ (149792676) stratum_task: rx: {"result":true,"error":null,"id":36816}
₿ (149792686) stratum_task: message result accepted

I understand some of it, but would be nice to understand more:

a) minimum difficulty is set by the pool to be 971. Is it 971 times more difficult than the base difficulty of 1?
b) the first result is ignored because its hash's difficulty of 498.6 is below the set limit of 971.
c) nonce F31C000D is transmitted to the pool as well as the verification 2197C000 (although verification was transmitted as 0197c000).
d) the result was accepted by the pool.

What do the other numbers mean?
