Sort:  

It's random, but not entirely, since it has somewhat a predictability, therefore it's seasonal.

There are no intersecting lines, it is just joined together smoothly. It's like if you put oil on top of water, they don't mix together, but you can also hardly see the boundary. The more you "zoom in" the more clear it gets, but the less accurate.

The best estimation here is that the local probability distribution changes every 49 days or observations.

Lol, this is splendid. I really do take my hat off to you. If this was a fairground I would have crossed your palm with silver!
