"I think the best way to approach this is to not expect Super Huge grades from BMK as this would Tell the Market that ONLY high grades are rewarded and something like 1-3% Ni which would be usually Outstanding would fail to have impact on Sp."

You can decide to expect anything you want, but it will have no effect on the market response. If the numbers are sexy the market will respond, if they are good but nothing the market can understand immediately then the response will be more gradual.
