TLDR: making cite requirements so specific will steepen the difference between IPS and the rest of SE, making it even less of a good fit, and annoying crossover users all the more.
If a person does a good job citing life experience, they might have 2-3 such instances of life experience. Now, they need to cover those four points you mention, which means they need to describe the life experience sufficiently to frame it in context. These requirements, plus making it coherent, create a certain bulk. As this life-experience reference becomes a full-on anecdote.
And then, these anecdotes start to become the bulk of the answer's real estate. So the answer appears to be less an answer to a question, and more a collection of war stories.
This invites more and worse, from newusers particularly.
This can be done well... and refined further. The problem is, it won't. Newusers can't, because they simply don't have the honed skills that the IPS regulars gained by long experience, iteration and meta discussion. This is another notch on the already-high skill levels needed to effectively answer here - already the highest in StackExchange.
This worsens a problem that's already quite bad, of IPS perceived as being hostile to newusers, and run by an inner circle that seems arbitrary, capricious and cliquey, and dislikes anyone else's contributions. What's actually true is there is an inner circle who shares the technical expertise to contribute correctly to quite high community standards. They have climbed a learning curve others have not.
Snything you do to make that learning curve steeper, needs to (at the least) be explained even more clearly to a StackExchange member crossing over from another site, which already has a serious expectations mismatch due to differing editorial standards.
In practicality, I fear that won't happen and it will only distance IPS from SE norms even further. Requiring posters to disclaim personal experience is already a stretch. Doing so in such specifitiy is a big stretch.
You'll need to help users do this - much more directly than a FAQ.
