If the missing gaps form a pattern, strictly speaking yes it would be considered a broken storyform.
However, the intention of the author would make a difference on whether it happens, I would imagine.
Let me explain:
Usually, if an author is deliberately (with intention) leaving out a pattern of story points, that would mean the author knows storyform and consciously leaves out specific patterns he or she knows would affect the audience in a particular way.
Alternatively, if an author - let’s say a less aware author - left out storypoints, it’s unlikely there will be a pattern in it...because he or she isn’t aware enough to know which ones will do the trick. Of course, there is always luck!
I was a bit worried about the missing storypoint pattern thing myself because I’m still learning and it is likely I would’ve left out storypoints in my own stories. Did I intend to do that? No. But I could still inadvertently do it. In that case, my readers, I hope, would’ve informed me.
. Feel free to ask away. Sometimes the best way to get this info to stick is to explain it to someone else. So, you are doing me a favour :))))
