It shows the voltages a period of time. Days I think. We would all be shocked if they did a test in Mexico. Our Dynasty has an EMS. I went into the shop one day and the power in the MH was off. Lights in the shop were OK . I called the CFE and the lineman that came out tried to tell me that 134 was the Mexican standard. I did not buy his fable. He explained that in a tourist area they keep it high because otherwise it is too low on the weekends when the town is packed. He finally adjusted the output on the transformer. It is now at a safe less than 130.

commercial/industrial electrician of 33 years here, and you would be correct that 130V will not harm a thing. Completely acceptable, and some of the power companies in GA have their transformers tapped to achieve that voltage for the same reasons, to allow for voltage drop during the summer months when they are under huge loads due to A/C usage.
