Works likes a charm. I know use:
  -filter_complex \
    "   [0:v][1:v]    overlay=0:0:enable=between(t\,0\,7) [stage1];
     [stage1][2:v] overlay=0:0:enable=between(t\,40\,45)  [stage2];
     [stage2][3:v]overlay=0:0:enable=between(t\,105\,110) [stage3];
     [stage3][4:v]overlay=0:0:enable=between(t\,210\,214) [stage4];
     [stage4][5:v]overlay=0:0:enable=between(t\,270\,275) [stage5];
     [stage5][6:v]overlay=0:0:enable=between(t\,306\,310) [stage6];
     [stage6][7:v]overlay=0:0:enable=between(t\,415\,421) [stage7];
     [stage7][8:v]overlay=0:0:enable=between(t\,515\,523) [stage8];
     [stage8][9:v]overlay=0:0:enable=between(t\,622\,642) [stage9];
     [stage9][10:v]overlay=0:0:enable=between(t\,722\,792)" \

That saves me a lot of time. :-D
