I honestly don't know. Special Intercept doesn't seem to look at power as it automatically scales your Nikke to level 200. However, it may look into more factors such as what cleared the stage. For example, Altstein(the train), is the single hardest Special Intercept and barely anyone aside from whales have cleared it legitimately. So they could factor in that along with Nikke skill levels, clear time, or many other variables. I'm trying to get a few accounts back at that point to continue testing, as I do not want to risk that on my main account.
