With reference to support ticket 992325 where the behaviour of making minute changes to the measurements of grid columns occurs inadvertently I would like to suggest that this is changed and does not happen, i.e. improve the handling of floating point numbers in the serialization/deserialization process. It causes noise in the source control history of the file. Note that this behaviour is not apparent with comparable reporting solutions, e.g. SSRS/RDLC files.
