Boy I sure wish data was this accurate and available, but even putting biases and agendas aside, even the most good-faith report could not produce accurate numbers. The fog of war is very real and it'd be nearly impossible to always assess whether a Russian IFV was "destroyed" or merely disabled and will eventually be repaired and back in action.
Sure would be great data crunching to actually have these real numbers though.
The US federal government values the average citizen's life at something like ~$12 million. This is mostly for policy like if 1,000 people a year die from something, say an unsafe ferris wheel design, a solution that would save them costing more than (1,000*12,000,000=)$12 billion would be rejected and considered not worth the economic cost. If the solution were cheaper, and cost like $500 million, then with good lobbying and a reasonable administration, it could easily become a new regulation.
Generally speaking if 5 anybodies went down like this submersible, you'd expect at least some millions to be spent in recovery missions.
The ~$12 million figure is what the NHTSA is currently using for its purposes.
