kaldari added a comment. I agree with Daniel that the magnitude of the uncertainly interval should match the magnitude of the least significant digit. In other words, the default precision (if none is specified) should be +/-0.5, not +/-1. The whole point of significant digits is that you can assume they represent an error interval that is equivalent to the magnitude of the digit's place. In other words, if you measured the quantity more precisely, and rounded to the original significant digit, you would still get the same value. If that isn't true, you're supposed to add an explicit margin of error (e.g. +/-100). By having a default precision of +/-1, we are suggesting that no values in Wikidata can be taken at face value (i.e. 845.2 might actually mean 845.1 or 845.3). This is both confusing and inaccurate (in the vast majority of cases).
