A white boomer has no soft side, so these are its only numbers. Times are exact for melee and for anything fired: swings times swing delay, or shots times fire rate plus the reloads that forces. For a charge you place by hand it is one second per charge plus the fuse, and that one second is the only estimate here. Melee tool counts assume fresh tools, because repairing lowers a tool's maximum condition each time and that rate is not in the files we read. Vanilla server settings, contact range, no distance falloff.
