Thank you for picking this up, the people of Purple Cress. While I think that Yuru Scans did it better (in terms of tidiness and text flow), I'm just glad I can get my dose of Sunohara-ara again.
As for the optimal time for uploads, any time is good as long as it's consistent. I'm sure everyone who reads this are from all over the globe so the only thing that matters is that they can expect a new chapter at the same time every x day.
