how often do you expect (or will allow) Waze countries to modify these ranges? If e.g. twice a year would be appropriate, then we could set the bounds tight enough (+- 0.20-0.30 €), in order to prevent mistypes and/or abuse, and regularly update them as necessary. Otherwise the bound are, IMHO, useless, especially in the mentioned form 1.000-2.999.
