I only ask because your personal account of 100+ jobs, at 5 mins per application, doesn't seem like the best approach to me. When I was jobseeking, I'd research every job description & company thoroughly first, and if it seemed like somewhere I'd want to work then I'd spend probably 20 minutes or so writing a cover letter that came across as personal.

I'm sure our experiences aren't apples-to-apples, but I definitely got a very high response rate from taking this approach.
