We already told the realtor (the union) what we want. Their job is to find us a house (TA) that meets out standards and we get to decide (vote) on if we like it.
I'm not sure that's what the OP wants, but it isn't anywhere close to what I want. I want information for my own decision making, not to win any debate and not for post-negotiation valuation purposes.
I think we told the realtor (the union) that we prefer blue houses over green houses and green houses over yellow houses. While that may still hold true, learning that I could get 4 green houses for the price of a blue house, or 12 yellow houses for less than half of that could influence the house(s) on which I write an offer. I may still prefer blue, but understanding the rough price to get one may (or may not) alter my direction to the realtor (negotiator).
As our input to reps currently stands - completely agnostic of contractual value because we don't know the relative value/cost, negotiators are left doing the cost-benefit analysis alone. Maybe their decisions mirror my preferences and maybe they don't. There were at least some level of effort weighting questions in the polling. I think more information is better, and am quite sure that even rough valuation estimates would improve the quality and relevance of my own input and likely that of others.
