If I did know, I wouldn’t need to consult them. Though, I’d imagine they use a similar technique to how I would appraise the value of a gaming PC, not that I’m an expert on consumer hardware pricing, but I’m fairly knowledgeable. But I would use historical data, performance metrics (although this wouldn’t apply to retro games), market conditions, conditions of the parts, and a certain amount of speculation.
The reason I’d look for a consensus is to account for outliers. If one expert is using some metric that causes them to over or under value a game, I’m less likely to get ripped off by having multiple expert opinions forming a consensus than if I relied on just that one expert’s opinion.

So you don’t actually know what sets the value of the games you buy, you just assume the value is set in some rational manner.
I’m not sure what is leading you to make such an assumption.
