Reading an old salvage manual and the decompression times shocked me

I was looking through a 1970s diving manual from a library in Seattle and saw the table for a 200 foot dive. The required decompression stop was over two hours, which is way longer than I thought for that depth. Has anyone else come across old dive procedures that seem crazy by today's standards?

But maybe those old times were more careful, not crazy. They didn't have the tech we do now, so they built in a bigger safety buffer. Makes you wonder if we're cutting things too close these days.

But what if they were just guessing and we actually know more now?

That two hour stop makes me wonder, like michael_jenkins39 said, if they were just being overly safe back then.
