Ok so the shipments are broken down into quarters.
If SYQ has 150kt per year average to sell, then PLL will be entitled to purchase 113kt of that quarterly product.

113kt is 75.3% of 150kt
therefore if in a quarter, we produced 37.5kt (one quarter of 150kt) then PLL would be entitled to 75.3% of that 37.5kt. That would entitle PLL to purchase 28.23kt at a cap of $900/t

I do agree with Whisky that i wouldnt expect each shipment to be split precisely this way, as long as over the CY PLL have had the privledge to purchase 113kt of the 150kt. This is why its imperative that SYA get to nameplate as quickly as possible.

This calendar year (2023), PLL are entitled to 56.5kt of product at $900 cap (the OT is based on CY as far as im aware)
so the first shipment most likely could be 50/50 and the OT will still be honored, regardless of whether we are at nameplate or not.
