I am a mere mortal, if I attempted to answer all of that it would be a very long post, and aspects would need a background in accountancy and finance. I mention accountancy and finance, as those who have an in depth knowledge outside of the inner circle of BCFC could not answer your questions either regarding Ashton Vale, and they have attempted to use brains larger than mine [yours?] to unpick what little detail was provided. Colin Sexstone at one Q&A could not answer points about financing a new stadium. Why not contact the supporters trust, fans parliament or attend a Q&A with Steve Lansdown? Questions regarding facilities for media would be easily answered, and more succinctly than I could manage. You could also contact the head of Bristol sport, who has more than implied the club will not be at a financial disadvantage at a re-developed Ashton Gate. As it is I disagree with an intrinsic underlying aspect of your post. My view of what essentially a football club is would not be driven by spread sheets.

MG started by saying what a great success the fans consultation sessions have been. They have complimented the creativity of the design team. He thanked the Fans Parliament members for their input. MG ended with: “We have come a long way and further consultation will take place in the next four weeks. This will be the last chance for change before the plans are submitted Yet to see even one picture of any design in process.
