No idea. I was only able to assume the time when they start subbing. There's no fix date for next subbed episodes. Remember how Wanthong (Got stuck after episode 6 for weeks) and Ley Luang (Got stuck after episode 4 for weeks)was subbed.
I don't know if I'm right or not but I think I've caught a pattern. GMM ONE seems to be subbing their primetime shows on the week when Episode 5 and 6 of that show gets premiered. It happened like that with Krachao Seeda and Ley Luang.
