I am still unsure about when to use 'would' and when 'will' while making conjectures about the events in the past. Is the difference merely in the degree of certainty?
Besides, I am not sure what difference is between:
- It won't have BEEN millions... (stressed main verb)
- It won't have been millions... (unstressed main verb)
