I think I understand what you mean, Croc was the first of that genre with the story limited to 1000 chapters and every day is 1 chap.
Croc author could have got the idea from this manga, or another one with the same premise released before that we don't know about it, the idea could have been used before easily.
The 100 days manga made from the Hayate mangaka is a failure for me too, not as much as the 2 getting close pretty fast and the ending being clear but the author being unable to keep the genre style on, I put it on hiatus and will read it n a go when it ends.
For being clear, thatmangaka made like 4-5 of chapters flashbacks of what happened in a single day, therefore it didn't respect the title.
It happened not even at 30 chapters so I can only imagine it getting worse.
I understand the author being busy with his weekly manga, but he should have done longer strips or a different plot development, he just jumped on the trend not ready for the work.
