Tried this Buddy Excitement guide and couldn't get it to work — is it outdated?

I found this older infographic explaining how to get a buddy excited without using a Poffin. I've tried following it several times, but my buddy never reached excited status within the expected timeframe.

Has something changed in the Buddy system since this guide was made, or am I missing a step?

Edit: Thanks everyone, I got my answer. The issue was me not interacting 15 mins after set 1!
