Bear in mind that the charted dataset is not complete, likely due to space and visual display comfort. Data really goes back to the 24th of January 2018 (starting with outliers there too for obvious reasons). It will be interesting to see what you come up with that may shed some new light over what has already been said in the past. Remember that not everyone here is stat savy, so the easier the concepts the better for assimilation by a broader audience.
