The key was 'continuous' hashrate. A huge chunk of doge's hashrate comes from auto-switchers that are only mining on probably 30% of doge blocks.
The numbers on bitinfocharts are 24hr averages. They take into account fluctuations in hash rate between individual blocks.
Doge is a joke, albeit a profitable one for the time being until interest dies off.
Maybe the fact that it doesn't take itself quite as seriously as most other altcoins is one of the reasons it's been so successful
