One thing that I cannot get enough information in the internet is what constitutes as a `share` in pooled mining.

In pooled mining, each miner gets a target difficulty by the pool. This target difficulty varies pool-to-pool.

The ASIC miner tries to find a solution ABOVE this target difficulty. Typical log looks like this:


Now from the pools perspective, what are my shares?

Are they

1024 + 1024 = 2048
Or
2914.8 + 1168.5 = 4,083.3

I do know that the hashrate is calculated using target difficulty of the shares w.r.t time.

But I am confused about the shares that the pool track.
