Peak concurrent viewers

Every stream has one moment when the most people were watching at once. That count is the peak. Streamers quote it, sponsors ask for it, and it gets read as the score for the whole broadcast. A peak of 2,000 says nothing about how many of those 2,000 stayed, so average concurrent viewers is the steadier read. Track the gap between the two across a run of streams. A narrowing gap means you are holding people; a widening one means you collected a spike.
