Braking action reports and runway conditions are two vastly separate issues.
Boeing provides data dry, damp, wet etc it has no relation to a RCC provided by vehicle doing a braking action report.
Operators have merged the data in the interest of safety but in reality they’re meaningless. Even Boeing hasn’t tested all stoping actions and a lot of it is calculated.
The question in this case is what runway condition was given to the crew, wet <3mm or contaminated?
