Вариант: 1. Open Space, Wind, Breath, and Windage: Physical Factors
Open Space:
A graveyard is typically an open, unobstructed area—flat ground, scattered tombstones, no dense foliage. This aids visibility (moonlight glinting) but exposes the monowire to environmental interference like wind. Unlike an enclosed space (e.g., Hogwarts corridor), there’s no shelter to stabilize the wire’s path.

Wind:
Even a mild breeze (e.g., 5-10 mph, common at night) would affect a filament as thin and light as monowire. Its low mass and high surface-area-to-weight ratio make it prone to drift or oscillation, like a spider’s thread in air. Stronger gusts (15+ mph) could tangle or divert it entirely.

Impact: In an open graveyard, wind would disrupt HJPEV’s intended trajectory, especially over distances (e.g., 10-20 meters to reach all Death Eaters).

Breath:
HJPEV, bound and stressed, might breathe heavily, and nearby Death Eaters’ breaths (or Quirrell’s monologue) could generate micro-currents. While minor compared to wind, close-range exhalations (e.g., 1-2 meters) could nudge the wire, especially if it’s near a target’s neck.

Impact: Subtle but cumulative—breath could wobble the wire at critical moments, misaligning cuts.

Windage:
Windage refers to a projectile’s deviation due to air resistance or crosswinds. For monowire—assumed to be near-weightless and flexible—windage would amplify drift. Unlike a bullet (rigid, high momentum), the wire’s lack of inertia means it’s easily swayed, requiring constant correction.

Impact: Leading it across multiple targets in a windy graveyard would demand precision beyond human reflexes, especially under capture stress.

2. Difficulty of Leading Monowire Along an Arbitrary Trajectory
Physical Challenges:
Control: Guiding a near-invisible, ultra-thin wire through 3D space—over meters, around obstacles (e.g., tombstones), and into precise neck-level cuts—requires superhuman focus. HJPEV uses wandless magic or mental intent (transfiguration), but wind and breath would introduce chaos, bending or curling the wire unpredictably.

Speed: The wire must move fast to kill instantly (e.g., 10-20 m/s for decapitation), yet HJPEV must adjust its path mid-flight to hit multiple moving targets (Death Eaters shifting, breathing). This demands split-second recalibration against windage—akin to threading a needle in a storm.

Visibility: The text notes the wire glints in moonlight, implying some reflectivity. In an open space, this should alert Quirrell or Death Eaters (e.g., a flash as it moves), yet they don’t react—narrative contrivance. Realistically, HJPEV’s own sightline (bound, possibly at an angle) would struggle to track it.

Mental and Magical Effort:
Concentration: HJPEV, under duress (captured, facing death), must maintain perfect mental control over a dynamic, wind-affected filament. HPMOR implies transfiguration is intent-based, but real physics suggests this exceeds human cognitive bandwidth—akin to juggling while solving equations.

Magical Feasibility: Even with magic amplifying precision, the wire’s fragility and environmental interference (wind, breath) would resist arbitrary paths. A straight cut might work; a complex, multi-target arc strains credulity without explicit spell support (e.g., levitation charms).

Realistic Difficulty:
In ideal conditions (still air, short range), guiding monowire could be plausible with magic—say, difficulty 7/10 due to focus and precision. In an open graveyard with wind, breath, and multiple targets, it’s near-impossible—9/10 or higher. Windage alone could derail it, and HJPEV’s capture stress (no calm prep) compounds this.

3. Narrative Contrivance vs. Realism
HPMOR’s Framing:
The text ignores these factors—wind doesn’t sway the wire, breath doesn’t nudge it, and its glinting goes unseen. Quirrell’s monologue and Death Eaters’ clustering (visible to HJPEV) rig the scene for success. This flattens the intellectual challenge, making it a Mary Sue win—HJPEV’s “genius” isn’t tested by physics, only by plot convenience.

Example: His plan works because the world bends (e.g., unnoticed wire), not because he accounts for windage.

Realistic Outcome:
With wind (5-10 mph), the monowire might drift meters off-course, missing necks or tangling. Breath could wobble it at close range, and windage would scatter its path over 10-20 meters. Leading it arbitrarily—curving through 30+ Death Eaters—would likely fail without godlike control or a windless vacuum. HJPEV’s capture (bound, stressed) would further erode precision, making success improbable without narrative fiat.
