Here's some examples of spoiler releases since 1016 (EST)
1016: Jun 8th (Tuesday, 10:09 PM)
1017: Jun 22nd (Tuesday, 7:36 AM)
1018: Jun 29th (Tuesday, 7:51 AM)
1019: Jul 13th (Tuesday, 7:57 AM)
1020: Jul 21st (Wednesday, 12:48 AM)
1021: Aug 3rd (Tuesday, 8:51 PM)
1022: Aug 10th (Tuesday, 8:27 PM)
1023: Aug 24th (Tuesday, 5:56 AM)
For reference, its currently 6:16PM EST right now. As you can see if Korean spoilers (or Redon) do not leak typically Tuesday Morning EST, they leak sometime Tuesday Evening, which can be anywhere from 8:30PM to after midnight Wednesday.
So based on this, earliest in about 2 hours. Latest in about 6.5. However this could just drag until the following day. I doubt it though, based on the last 8 chapters.
