Your Step 2 CK - Step 1 Gradient!

I noticed that most of my friends have scored higher in their CK exam than in their Step 1 exam.

So in this thread let's see if that has happened with you also. Let's call it the Step 2 CK - Step 1 Gradient. Which means how many score points your Step 2 CK score was higher than your Step 1?

The formula is
USMLE Step 2 CK Score - USMLE Step 1 Score (three digit scores for both)

For example if you scored 212 in Step 1 and then scored 222 in CK then your gradient is +10. Or if you scored 192 in step 1 and 190 in CK then your gradient is -2.

What is the benefit?
Well, if we can get an average gradient from our members we can then come up with a magic number that can predict your next exam no matter which one you take first. Like if we concluded that the average gradient range is (+11 to +20) for example then when you take 200 in Step 1 you can then expect your CK score to be 211-220 even before you take the exam. It works the other way round also (i.e. always predicting your next exam from your first exam no matter which exam you take first).

So let's start...

Here's my contribution
My Step 1 - CK gradient was +25.
