They do tell you if the budget was short or not. Just not which line items were short, and it is usually a year behind.

So this is telling me that the budget was short 855,111 for 2022. You could divide that number by the total number of points to see what the shortage was. Basically DVD doesn't pay dues on the unsold inventory but they guarantee that they will make up the budget shortage every year if there is one (and they get the budget excess essentially, if it exists ever up to a max of what the dues on their points would have been).
Remember DVD is a different entity than Disney. So the points that Disney retains as the 2% ownership they do pay dues on. This is simply the dues they don't pay on inventory DVD is sitting on to be sold.
You could go look at 2022 to 2023 and see what the line items look like, if they want up assume that actual expesnes were over budget in 2022 and vice-versa.
Edit: The developer guarantee has usually been a positive for members from what I can tell looking at historical budgets. It is just DVD probably does it given that it is a huge advantage to them when they first selling a resort. And to only have the guarantee on the new resorts would seem weird to owners so they apply it to all resorts.
