Well,the title says it all...

Counting are decaps of the enemy with no previous dismember, biggest engage distance counts...

EDIT: Well, I now read the instructions...

Title: Widest Head Throw With 1 DM Treshold

Preferences: DM Treshold=1 Engage distance=record

No Mods

Here's my try... feel free to comment (only "Oooh" and "Aaah" are allowed)

EDIT: It's 640 frames, I have been too lazy to try the maximum distance in single steps...
