  base.number as NR,
  rank.rpo as RPO,
  rank.rsp as RSP,
  rank.rsv as RSV,
  timer.t3m as T3M,
  timer.t1g AS T1G
FROM

  round LEFT JOIN base 
  ON round.id = base.round_id 

  LEFT JOIN rank 
  ON round.id = rank.round_id and rank.number = base.number

  LEFT JOIN timer    
  ON round.id = timer.round_id and timer.number = base.number

order by T3M DESC
  ) q1, (SELECT @row:=11) rows
) q2,  (SELECT @row:=11) rows
ORDER BY
  T1G
