Disclaimer: My experience is my own and is by no means the definitive and only voice for everyone else's experience. Read up on what you can and take away from what you will and form your own opinions from your own experience. Although I hope what I have shared will help shape a better outcome for those reading it. I was new to a vast majority of TT'ing techniques and a lot of the information was overwhelming at first, but don't fret, it will all make sense as you begin to apply the concepts. You may fail and suffer dire consquences, but you would be wise to learn from it.

This is the first serious method I've used since playing ACNL and I can tell you it's worked out flawlessly in my experience so far. I haven't read every page on here but I would like to share my experience. But first, here are some condensed take-aways in case you don't want to dive into my post:
- Have at least 2 informants, this is practically imperative as my story below will tell you.
- Greet new incoming villagers ONCE the first time they move into your town even if you hate them. It will take them a lot longer to move out otherwise.
- Don't wait for a ping from a villager you're hoping to move, trust in your 2 informants to provide that information.
- As your TT'ing, don't forget to also chat up your other favorite villagers if you want to keep your dreamies especially! I started with just Genji and Bruce as favorites but I quickly amassed other dreamies. Talk to all your favorites multiple times as if they were your first 2 informants. They may also shed light on who's thinking of moving.
- Completely ignore the villagers you dislike aside from the first greeting when they moved in. Ignore them even if they ping you, for whatever reason. Case in point:
In Yuidere's case... As I've read other examples of this, where villagers will ping you asking to move and you have the option of telling them to stay or to get the heck out. Sometimes, when you tell them to go away, that villager may SPITE you by saying they'll stay instead. This is why I say you should ignore them completely, even if they ping you. Let your informants gossip to you that that villager is moving and then wait as you TT one day at a time for Isabelle to tell you that villager is at last, finally moving the next day. I'm sure the action of the villager depends on their personality as well so it's just all around a safer bet to ignore them even when they ping you.

In the tutorial, it specifies to pick 1 favorite villager as the informant. As others previously in this thread can attest, it's good to have at least 2 and I had no issues with that starting out as Genji and Bruce were my only favorites at the time. This came in extremely handy because often times,
1 of them would inform me when someone was moving but hardly ever both. They're also 2 different personalities; not sure if that makes a difference however. Genji is a jock type villager and Bruce is a cranky type villager.
On one of my TT'ing adventures, Genji got sick for 3 consecutive days. I gave him medicine every day until he was better but during that time, he didn't want to talk about anything other than him being terribly sick. This is where having a second safety net like Bruce came in
super handy.
I will also state that as I'm TT'ing one day at a time (aside from TT'ing max of 4 days forward when someone just moved in and is completely unboxed), that it was good that you talked to ALL of your favorite villagers multiple times so that they feel they're still loved in a sense while completely and utterly ignoring those you wanted out aside from the first greeting when they move in otherwise, as tutorial says, it will take them a long time to get their arses out of your town. I can attest to that by experience:
For example, I had Chadder the mouse move in. I failed to greet him the first day he showed up. In that time, when Barold and Eunice moved in after Chadder, I greeted them once when Isabelle told me someone has just moved in. Fast forward a bit as I was TT'ing, Barold and Eunice have already moved out while Chadder still remains. TT__TT Basically, you would think Chadder would leave before Barold and Eunice but he's still around! I failed to greet him in the beginning and now it's taking him quite some time to get out.
This technique still worked whether I had 9 villagers or 10. Although I will say it is not impossible for a villager to move out when you're at 8, as I've had it happen with this technique but regardless, I knew who was moving through my informants.
so now she'll be living in my cycling town until I've gone through 16 villagers in Moga.
