@jan There are dozens of ways that someone could have a "sort of" response, and I like to leave space for those. I don't think I can enumerate them all.
If you struggle to understand how some questions that seem absolutely binary to you may be less so for someone else, that's OK. If it's really important to you to get exact numbers, consider making your own poll without the "sort of" answers. Or you could enumerate all the ways someone could "sort of" have gone to a laser light show.
