Seven deduction grounds in one letter mean seven separate pieces of research.
The insurer gives a reason for every deduction, usually in half a sentence. Transfer costs, blend painting, hourly labour rate: there is case law on every keyword, and it is rarely in the same place. The research falls to whoever has time, and in the next case the same search starts from scratch.
