Now if I think about that it seems there might be some pattern in my case:
1. I believe my mum is 164 and my dad 749. Both have type 4 in their trytipe, it's not their core type though. However, I am core type 4.
2. As 469 I share other two types (not core) in my tritype with at least one of my parents types (also not core).
3. There is a connection to my mum's core type through my wing (9w1 in my tritype).
4. The only type I don't have any clear connection to is my dad's core type (7).
5. Words type and tritype sounds ridiculous after being used so many times in this short paragraph...
Curious to see observations of others.
