Watch the orange square. It’s just one with a difficulty from 19 to 24% seems alright.
Then watch this. The difficulty could be higher, but there are no squares.
Finally, this. The difficulty could be 56% but its just one square.
What I’m saying is that this is kinda misleading, i know one can immediatly watch the percentages, but still. I suggest to have the orange squares go in accordance with the highest difficulty percentage.
