@dr.sybren The problem is in the file (line 574): https://projects.blender.org/blender/blender/blame/branch/main/scripts/modules/bpy_extras/anim_utils.py where it looks like I thought fcurve.update() would remove duplicates but it doesn't. So there are overshots (original keyframes) and the baked keys overlayed ontop eachother.
