> After all, by definition each decimal place is 10x less important. I’m not sure about that, since it depends on the error margin tolerance one has. Regardless, my biggest gripe with most reports of quantitative information I stumble across is that, lacking mention of significant digits accuracy, it’s very easy (and I’ve seen this happen a lot) for people to attribute more accuracy than what is there to a value. One example: AWS cloudwatch reports external replication delay in MySQL Aurora in milliseconds, which is impossible, since the value reported by MySQL is in seconds. Yet many times I’ve been involved in discussions with people who say “our system can tolerate at most 500ms” of replication delay for reads, because they see the value reported in that unit.
