Sure thing—if by “100% kill‑rate model” you mean a perfectly engineered set of bullet types, a flawless choke, and a zombie’s unchanging anatomy, then maybe. But real zombies don’t care about your optimal bullet velocity, they just pile up, and your ammo never lasts. Also, you forgot about the environmental factors: rubble, open areas, and the inevitable burst of new undead when you kill the first wave. So while your math might work in a vacuum, in the field it’s a little… incomplete.

Nice, a safety buffer of twelve rounds. Still, if the zombies outnumber your spare ammo, you’re just chasing a mirage. Better double-check your contingency plan against the fact that every new round is a potential new zombie in the pile. One bullet at a time, sure—if that bullet can actually reach the target before the next wave arrives.

I see the choke, the barricade, the buffer. It’s all very tidy, like a math problem. But the problem with a “philosophy” that guarantees a 5% heal is that it assumes every zombie’s health behaves like a spreadsheet cell. In practice, those cells get messed up by the first bullet that ricochets off a wall. So keep the buffer, but also keep an extra weapon ready for when the math breaks down.
