Browsing through some pages - so far the ennegram scores and MBT user scores sync up. No real surprises. If you tested as ENFP and a 5 for instance I'd be surprised.
Lots of 4s for INFPs, 5s for INTXs, 7s for ENXPs, sounds about right.
Ennegram really doesn't fall into place the way MBT does. But learning more about the triads and how it's based on your motivating fear and way to escape fear - it's really helpful and also will help you understand your true ennegram type and how it can help you. There are pages online that explain to you why certain types commonly test as other types and how to distinguish what the difference is.
I have tested usually as a 3 or 7 and even as a 2 or a 4 (which I hated and railed against). But it was only after reading more about the "science" of ennegram that I stuck with 7w6.
