Every number in this card is at official 1× rates, with the fastest food. Taming speed and food consumption multipliers change all of it, and most servers are not on official — the calculator at the top of this tab takes your rates, a Sanguine Elixir, and every other food this creature will eat.
Effectiveness is what decides the bonus levels: every unit of food eaten costs a slice of it, so the food that needs the fewest units finishes at the highest level. That is why kibble is worth the trouble — not that it is much faster, but that it is fewer feedings.
