just curious, are automotive alternators rated at 100% duty cycles, like in aviation?

because the alternators i work on at the air field are all 100% duty cycle.

No, unfotunately there are no ratings police in the auto aftermarket. This is why we have so many companies out there with such high claims, because they know the majority of their customers dont have the tools or knowledge to test them and call them out on their BS!
