You are right that it is good to be conservative. But you also used 2,400 USD per ton ASP for the spodumene project, which is not far off from the current spot market price, depending on which source you look at. It's true that the spodumene ASP will react quicker to spot market price changes than the lithiium carbonate contracts, but I think four quarters is a lot of time for contract renegotiations and many contracts already contain variable market oriented pricing mechanisms. Than there is the narrow gap between battery grade and industrial grade prices in a market that is starting to be undersupplied. I think Allkem wants to achieve 50 - 60 % battery grade with the Olaroz project over the current and next few quarters.
