Both ranks and ratings have limited reliability. For some players, ranks are more meaningul; for others, ratings are more meaningful; for yet others, both contribute to relevant information.
Ranks derived from rating systems can differ from ranks of ranking systems. E.g., a rating system can start ranks 1/2 rank later than a ranking system.
Some systems are totally unreliable. E.g., the KGS rating system produces nonsense such as: real world 3d is 9d on KGS, a former European Champion can be 3d on KGS but is real world 6d, 80% winning can be not enough to increase a rank, 50% winning against equally ranked players can drop a rank, the best strategy for improving a rank can be not to play at all etc.
Usually, a person himself knows best his rank and reliability of a rating. Therefore, others should not "correct" it without asking. If a rank or rating is stated for a date and system, there is no meaning in altering the value for the given assumptions.
Yes, validity of contributions are not given by ranks or ratings but by correctness and verifyability of contents. Ideally...
