Avoid artificial inflation on both sides

Some negotiations develop like this:

“Mine is worth 1,200 instead of 1,000, so yours can be worth 900 instead of 750.”

The result may appear balanced, but it makes the real difference harder to understand.

It is clearer to keep both values close to realistic references and negotiate the difference directly.

Higher nominal figures do not improve the trade: what matters is the relationship between the two values and the real convenience for both parties.
