Feeding your tamagotchi food and skill points

[MyGotchiSmokes]

So noones said it yet, I assume everyone else knows this, but

I think your Tama has to actually be hungry in order to get any points outta the deal...

You cant just cram a buncha sanwiches down its lil throat and hope it gets any smarter

Am I right?

Is there a similar chart for v4.5?
