How to find the index:

1. open engine module
2. string search "@%.03f:loss(%.05f)" and go to its only xred which is cl_move
3. create pseudo

          if ( v32 <= 0.0 )
            {
              if ( v30 <= 0.0 )
              {
                if ( dword_1058B414 & 0x1000 )
                  goto LABEL_57;
                if ( *(_DWORD *)(dword_1058B41C + 36) )
                  v14 = *(BYTE **)(dword_1058B41C + 36);
                if ( *v14 )
LABEL_57:
                  (*(void (__stdcall **)(BYTE *))(*(_DWORD *)dword_1058B41C + 56))(&Data);
              }
              else
              {
                v21 = sub_10027F70(v19, (int)&v26, (int)"@%.03f:choke(%.05f)", v31);
                (*(void (__stdcall **)(int))(*(_DWORD *)dword_1058B41C + 56))(v21 + 5);
              }
            }
            else
            {
              v20 = sub_10027F70(v19, (int)&v26, (int)"@%.03f:loss(%.05f)", v31);
              (*(void (__stdcall **)(int))(*(_DWORD *)dword_1058B41C + 56))(v20 + 5);
            }
          }
        }
        else
        {
          (*(void (**)(void))(**(_DWORD **)(v3 + 156) + 104))();
          v11 = *(_DWORD *)(v3 + 156);
          v32 = result;
          (*(void (**)(void))(*(_DWORD *)v11 + 88))(); <---- this vfunc call is createmove divide the last number: 88 / 4 = 22. 22 is the current index.
