A break can be any amount of time, enough for Shonen Jump to state at the end of chapters if there will be a break before the next one.

“YES” = “Yes, there will be a break after chapter 70”

“NO” = “No there will not be a break after chapter 70”

Plan to close this on official release, will close earlier if known-accurate leakers post any details about a break ahead of time. I do not vote in my own questions.
