Well the NEC still uses wattages from old incandescent bulbs for general lighting load calcs, plus there’s always a reasonable amount of overspeccing built into the calculation.

You would then add any large loads specifically. Clothes drier, oven, fridge, HVAC, anything that comes with a nameplate wattage rating should be included in the load calc.

Most utilities these days will also just round up to a 200A service for anything larger than a trailer. Big houses would get multiples of 200A services if needed.

Lighting load on new construction homes is calculated based on square footage.

I have an android TV, but there’s obvious problems there too.

The surge of Chinese accounts logging in during February is because of Chinese New Year, not bots. Most Chinese people get like two weeks off work for the holiday, so the number of Chinese people playing at gaming cafes (which are exclusively windows) spikes like that every year.
