Yeah, the test isn't really very accurate. And if you're getting close on both axes that mean the test is actually telling you it isn't sure! (this doesn't mean your personality is actually close - it means the test doesn't know).

There are better tests (like this one https://sakinorva.net/functions) which will give you a confidence percentage for each cognitive function rather than just a best guess overall type. But none of them are that great, and currently the gold standard for determining type is to only use the test results as starting to point and to familiarise yourself with the theory to fine tune that, potentially with the guidance of an type expert.
