Thanks for the advice. I doubt that my employer would be willing to re-word the offer. My current ITA deadline is March, 7 2018, still some times to go though. As you said, this 50 additional points is not guaranteed. I shall see what I'd want to do. Speaking of the points, do you know if the points that generated by the CRS calculator is somehow different from the one showing on your profile?
The CRS calculator is accurate (if you fill it right of course). But you can simply logged in your account, retrieve your "Overall Score" in your EE profile and subtract 50 points.
