Another question, I'm reflecting on:Ore missed the nameplate...

Another question, I'm reflecting on:

Ore missed the nameplate several years. I assume, that they pumped enough brine in the ponds to hit the nameplate. 

So let's guess, they pumped enough brine in the ponds to harvest 18 000 tons Li-Carbonate / year.

At the end of year they just achieved let's say 14 000 tons.

Does that mean, evaporation just was slower, and there is still concentrated brine in the ponds,

that allows you to harvest another 4 000 tons later?

Or does that rather mean, that they just got 14 000 tons out of what they guessed, they will get 18 000 tons.

Any ideas on that?

Thx.
