Farming and Elixir Luck

[Sheugokin]

Hello fellow community members,
I have a question: How come when farming runs are periodically hosted by other team members does the drop rate go up? I tend to see that happen. Also, free 24-hour daily elixirs can be stingy, but after I wait a day without getting it and get the elixir for the next two days, I suddenly start getting 3X and other combos. Is it just luck on my side, or is it true? Does anyone experience this too?

Thanks!
