As soon as the results of a hypothetical practice bid are published a lot of pilots will change their bids, then when the actual comes out and looks nothing like the practice bid results, those that didn't get what they expected will howl about it's inaccuracy, and those that could of gotten something but didn't bid it because of the practice bid will howl about it's inaccuracy.

Fact is it won't be a much better predictor than the current "pilots in category senior to you bidding" tool.

Way easier and more fair to bid what you want and be ready to fly what you bid and let seniority rule.....
