I was quite strict in only marking questions the criteria of which I fulfilled 100%, there was a lot where I did so partially, or where the wording was unclear. For example if I've owned a book series, or read it once or twice doesn't necessarily mean I own it today. Or if I watched something when I was younger doesn't necessarily mean I still watch it, or even like it much. Or if I went to some book store once a week and knew the owners by name when I was 13 doesn't mean I do it aged 29.
