For Pavel and anyone else who is interested. I have updated the spreadsheet I posted earlier to include cash flow analysis for C-O and tried to figure out what the share price should be from present through 2030. Share price at the present is based on NPV and transitions to being based on multiples of cash flow. One can change the inputs to the model and see how they affect share price values. This is by no means perfect, but gives a fair sense of how changes affect share price.
