IS FREEZE SUBDIVISION LEVEL really bring back 100% detail ? when click “FREEZE SUBDIVISION LEVEL” button,you 3D model back to lowest detail, and if i use the New insert mesh function that make a new polygroup for mesh insert (no any affect out side this poly group i think =_=" ) ,after mesh inserted ,we turn FREEZE SUBDIVISION LEVEL off, now,can i assume that i don’t have ANY detail lose??

It depends on what changes you are making to the low res mesh. For the parts of the mesh that are completely unchanged, the hi res detail will be restored 100%. For areas you have changed - such as by inserting meshes or creating new topology - less or no detail will be transferred. Only you can decide whether the process is suitable for your workflow.
