1. Walking out on Wammy's House

   Minor evidence

   Death Note, Near and Mello arc

   After L's death Mello refuses to team up with Near, leaves the orphanage for gifted children and joins the mafia. It is emotionally driven, but it is also a strategic bet that a method outside the law could reach Kira where the SPK's methods could not. Going criminal gives him people, weapons and reach that Near cannot legally use. The choice is reckless and it is a real plan, which is exactly the tension that defines his estimate.

2. Kidnapping Sayu for a notebook

   Strong evidence

   Death Note, Mello arc

   Mello first tries to abduct the head of the police, and Kira kills the man before he can. He then kidnaps Sayu Yagami, the daughter of a task force member, and trades her for a Death Note. Picking the one lever that a team of detectives cannot refuse takes both nerve and a good read of his opponents. It gets him a concrete result against a group that contained Kira himself, and it is the strongest evidence for his planning.

3. Learning the rules and spying through Matt

   Moderate evidence

   Death Note, Mello arc

   Mello meets the shinigami Sidoh and learns about fake Death Notes, and he sends his friend Matt to spy on Misa Amane. That is a compact piece of investigation: find the right non-human source, learn the rules that matter, and put an eye on the person closest to Kira. The intelligence-gathering feeds directly into his later moves, and it shows he can pursue more than one line of inquiry at once, which brute force alone does not explain.

4. Escaping Light's raid

   Moderate evidence

   Death Note, Mello arc

   Light traces Mello's hideout and sends a SWAT team. Mello sets off explosives to escape and comes away with a facial scar. He gets out alive against a prepared, well-informed enemy, which speaks to improvisation under pressure. It also costs him, because Light walks away holding his real name. That pairing of quick thinking and a serious exposure is typical of how the story marks him, and it pushes the estimate neither up nor down by much.

5. Grabbing Takada

   Strong evidence

   Death Note, Mello and Takada

   Mello works out that newscaster Kiyomi Takada is tied to Kira and has Matt hit her motorcade with a gas grenade so he can take her. The deduction points straight at the person Light uses to hide behind, and the strike is well executed. It also scrambles Light's operation and sets off the chain that lets Near find the real notebook. It is the most consequential thing Mello does, and it is the reason his estimate reaches the high 130s.

1. A fatal oversight with Takada

   Death Note, Mello and Takada

   Mello captures Takada but does not stop her from using a hidden scrap of the Death Note. She writes his name, and he dies. The kidnapping was clever, and failing to control the one thing that mattered was careless. A top-tier planner covers the tail risk, and this lapse costs Mello everything.

2. Handing Light his name

   Death Note, Mello arc

   In the Sayu trade and the raid that follows, Mello ends up with Light knowing his real name. That is a serious strategic exposure against an opponent who kills by name. Light later turns that into Takada's instructions. The plan was bold; it left a vulnerability a patient rival would not have permitted.
