Our case is strong but the numbers are thin
The entitlement is well argued and the events are proved, but the quantum is a spreadsheet nobody in the team fully trusts.
What's happening?
It is the standard shape of a claims practice's workload: the people who win the entitlement argument rarely have three clear weeks to measure the claim, so the valuation gets whatever time is left. The submission goes out with a persuasive front half and a back half of round numbers, percentage uplifts and rates nobody can source under pressure.
The other side's surveyor reads it back to front. Every figure without a build-up is an invitation to discount, and the claim settles below its worth because the money could not carry the case the liability side built.
The repair is a valuation built from the records with its workings on show, so the figures make the same argument the submission does.
The solution
Put the same rigour under the numbers as went into the narrative.
