In my case 100 was not enough. I almost didn't sign up for Kagi because I hadn't yet felt the value and configuring a browser to use Kagi as the default search engine isn't a zero effort task.
It probably took me about 200 to 300 searches before I was firmly decided that paying for Kagi is worth it. If I hadn't been freshly mad about Google's declining search quality, and displeased with DDG for something they had recently done (can't remember at this point), after the trial I probably wouldn't have paid and just would have gone back to DDG.
