When people are older, the functions are harder to differentiate unless they're unhealthy for a while as they are much more balanced. I would ask what her interests may be when she was young and if she allows it may illuminate your understanding. Although my parents are very private about what they did as children which never really made sense to me, but yeah.
Define sensory intuition to me though?
Si is looking for a method to be comfortable in and enmeshed in. It would contradict what intuition is, as intuition looks past the surface and tries to see the inner workings of something. Applying a routine method is not intuitive by any means. Of course ISJ's don't live in a world where Si can flourish alone and may have to occasionally change their methods as life is ever changing via other functions.
I am starting to like the word "detail oriented" less for sensors, because practically every job description asks you to be detail oriented. INJ's learn details of things they are exclusively interested in to extreme depths if they so desire. But are they sensors? No.
