Ok, that sounds good. The example was more just to be illustrative. But there is the (slight) possibility of harmonics on the power lines, etc. There are EDA suites that can do such signal analysis on your board but they are quite expensive. If you picked just the wrong values there could be a filter system which amplifies noise from a power supply.
The trick is to get your board manufacturer to eat the return cost. If you can buy testing, do so; usually it comes with some assurance that the boards work, and they either make new stock or remanufacture what you send back. If you can point to a comprehensive testing instructions that the customer would have performed it should not matter if you receive the board and it works for you, for some reason it did not work for the customer.
