The top 10 can be obtained using this query in the SISPI telemetry viewer:

SELECT MIN(date) AS night_start,
       MAX(date) AS night_end,
       SUM(qc_teff*exptime) AS weighted_teff
FROM exposure.exposure
WHERE program='survey'
  AND object like '%DES survey%'
  AND qc_teff IS NOT NULL
  AND (dm_accept OR NOT dm_done)
GROUP BY obstac.nightmjd(date)
ORDER BY SUM(qc_teff*exptime) DESC
