Spodumene Price, page-804

I can see the perfect alignment to Asian Metals movement in that a $20 increase on $2,290 is 0.87% which would give $2,310; and taking the post before that, a $30 increase on $2,260 is 1.33% and would be $2,290. These calculations are an exact match to the latest daily change figures being quoted.

What I'm puzzled by is the relatively small size of the 30, 60 and 90 day increases. I was expecting them to be larger given historical Spod price estimates quoted in this tread around late Sep/early Oct (60 days ago) and late Aug/early Sep (90 days ago).
