An update including today's count:
Thursdays have stayed fairly consistent while Sunday has seen great volatility in terms of the troll counts.
This is evident from the graph and the mean/median/mode data: Thursday data is completely unchanged from the past 1.5 months of additional show data, while Sunday's mean is slightly lower but median has improved by 7.
Bullish on the Troll Index! Will keep this data updated every couple of months until I can automate it with some better webscraping.
