While most of the proof is good I feel that perhaps 1.66-1.88 ref would have been better seeing as there is only one bit of proof at 2 ref pure metal. It's a downvote for me I'm afraid. Also not many of the trades appear to have actually gone ahead yet.

Not sure the top end is justified, neutral for now but a sale or 2 for 2 ref would swing me.

Conclusion: Not sure about that top range, I see the majority for 1.66 and some under and some above.
