Can you please confirm a couple of things?
(1) Who are "the team [you] worked with" in the context of this?
(2) Who was responsible for the bundles if not your team?
(3) Why did you do the navigation document? Why didn't the people who put it together do that?
Bundles are huge documents that contain huge amounts of information. Whilst not being an expert on bundles, I believe that the secret to a good bundle is that it is organised logically, has no superfluous rubbish in it, no duplicates etc, and it has a very clear index / contents page / way of navigation. It seems to me that however logical and concise a bundle is, it is still a huge stack of documents and requires proper tools to enable navigation easily. If the bundle is illogical and has duplicates then the negative effects of this can be minimized by a having a great navigation system.
As an aside I was once a witness at a Tribunal Hearing - someone wanted £40,000 from my clients. Aside from only winning £4,000 they ended up paying all of my clients costs (very usual in that kind of Tribunal where the default is each side pays their own costs), and I believe that was partly down to the other side's case being so incredibly poor, and partly down to the bundles being so appalling and the Tribunal feeling that the state of the bundles cost my client and the Tribunal itself a lot of money.
