Use the Body map view instead. Enemies with a 3D tag in the list have a model.
Drop a .glb into models/ named after the enemy id (.glb), or load one with the button above.
Then use Edit hitzones to click each mesh and pick which wiki part it is.
Head
Arms & weapons
Body
Rear & weak spots
Legs
One-shot kills come first, sorted by damage (highest first); everything else is ranked by time to kill on its best hitzone in the current view. Time comes from RPM with the first shot at 0 s; reloads are not included (* = needs more than one magazine). Weapons without an RPM are ranked by shot count after timed kills.
You won't always hit the weak spot. For each weapon this takes every reachable hitzone in the current view that can kill, then uses the midpoint between the fastest and the slowest time to kill. Weapons are ranked by that midpoint.
