Step day by day as the app swaps out the kind of video Cara clicks least, until all four are Cooking. Then save one slot for variety and compare.
Each day, the kind on screen with the fewest clicks is swapped for more of her most-clicked kind.
Cara clicks every Cooking and Travel video she's shown.
Cooking starts at 2, from the two videos she watched. Day 1 shows one of each kind, and she clicks 2 of the 4.
