Just some thoughts:
1) What if Nintendo created Schroedingers console? They simultaneously won and lost the 8th generation with the Switch and the Wii U, respectively.
2) If we count the PSP as a home console, Sony actually won the 7th generation.
3) We could put Nintendo's and Sony's consoles into separate generations. That way, both companies will win 100% of the generations they partake in, as long as release schedules stay the same as they are now.

On a serious note: I think the best way to think about this is to simply look at yearly sales trends over a prolonged period of time and add both home and handheld (and hybrid) consoles to that. An actual market share graph.

How would PSP make Sony win the 7th gen when Wii & DS sold 255 million combined units. Nothing comes close to that number. PS3 and PSP don't come close not even PS2 and PSP. PS2 is not a 7th gen console so it does not count.
