Is it possible that my two highest scores were "idealist" and "realist"? It seems to be contradictory.
Your scores were:
45 Analyst
51 Pragmatist
53 Synthesist
55 Realist
66 Idealist
Only scores 60 and above indicate an actual preference.
I would not start comparing your Idealist and Realist score,
since your Synthesist and Pragmatist aren't far behind.
You have to look at what all your scores are really "saying."
I see an overall flat pattern with them, except for the Idealist.
That's why you scored 66.
Perhaps it's subconscious on your part, but it's there.
Wait awhile and then do a retest.
I have taken that test 5 or 6 times in the last 2 years,
and my scores have always indicated the same thing.
I'm a Synthesist-Realist. (Balancing contradiction!

)
If you're interested, I highly suggest getting Harrison and Bramson's book:
THE ART OF THINKING.
(A copy of the test is also in the book.)
I have it here on my desk.
It's a good read.
