Well, if your TODA is greater than your TORA (after rotation you're over a clear way) then you're unbalanced, so if the TO analysis artificially produced a clearway in order to unbalance a balanced field with the coresponding weight reductions, in order to produce that unbalanced field then you have and unbalanced field. In either case your ASDA can never be less than you're ASDR. as well you're TODA cannot be less than TODR. It would be helpful if you can provide a rundown as to how you do this analysis and what curves or tables you're airline requires you to have. but I assume most of you're operations are not BF... not sure if this is what you want but i tried
edited to add: if ASDA is much greater than ASDR then you can unbalance the field in order to produce a clearway i.e add some of the ASDA to the TODA, but it may require a weight reduction to ensure that the TODR = TODA
