Running discussion on SP, page-372

To be fair even if you try to ask him legitimate questions he blocks you. So who was there left to pull him up?

And to give an example I asked him how he calculated his -$20/t opex. Everyone here seems to quote it as fact so to say it had no influence is wrong. I even presented a case how I couldn't get Sn + Ta credits to offset even transport let alone Li processing.

His response was to block me. So either he couldn't prove it or he had sensitive information that he couldn't share the rationale. And blocking me closed down the conversation. Problem solved
