Well... if I think back to my teens and childhood, then I'd have said I was a very strong 5, in a non-healthy state. As my 20's progressed, I developed an 8-ish streak, and became increasingly 8-ish. I stayed interested in acquiring knowledge and understanding the world like a healthy 5, but by 30 I was approaching that and using what I gained from it from a much more 7-ish angle. This coincided with the variant I most related to going from quite strongly sp to very, very strongly so. The sx in me has gone from non-existant to now, just being explored, really. I guess what sp is left in me is what's holding me back from increasing the sx...?
If I look at the full scale of the 5, how they are at their absolute best and healthiest, that's not me, but how they are at their worst - or near worst - that's definitely how I used to be. I also can't see either of the possible 5 wings in myself. And yet, whatever period of my life I look at, I can still see the ENTP there, though sometimes, especially when I was up to 20-ish, I looked more like an INTP.
This is of course, all not taking into account the rather drastic and high impact experiences I had in my 20's, that would be enough to completely change anyone from their previous behavioural and thought patterns
