Source: Matthew Stewart, who posts screen time calculations to his Twitter.
Example: Here is his post for "Godzilla vs Kong" (2021): https://twitter.com/MatthewAStewart/status/1381754096407957507
- KONG - 31:02 (27.43%) 
- Brian Tyree Henry - 15:43 (13.89%) 
- Alexander Skarsgård - 15:40 (13.85%) 
- Rebecca Hall- 14:06 (12.46%) 
- Millie Bobby Brown- 14:03 (12.42%) 
- GODZILLA - 13:19 (11.77%) 
Thus, an equivalent market would have resolved NO (barely), as twice Brian Tyree Henry's screen time would be 31:26, greater than KONG's 31:02.
Further details:
- If Matthew Stewart has not posted any screen time data within 3 months of the streaming release of "Godzilla X Kong", I will resolve this N/A (I won't attempt to calculate this myself). 
- He seems to be fairly consistent, so I don't think that will prove necessary. 
i'm fond of this question, but i must admit there's no evidence matthew stewart is going to post it.

I did shoot him an email and never got a response. RIP. resolves N/A
@Ziddletwix does this guy take requests? maybe we tweet the market at him and see if he’s game to do it
