I would have said "more than 90%", but from ChatGPT: Prompt: "What does vast majority mean?" Answer: "The term "vast majority" refers to a very large portion or segment of a given group or quantity, often implying much more than a simple majority or over half. It suggests an overwhelming or significantly large percentage, typically used to emphasize that the subject in question constitutes the bulk or main part of the whole. For instance, if one says "the vast majority of people support a certain policy," it means that significantly more than half of the people, possibly upwards of 70%, 80%, or even more, favor that policy."
