I think I found the reason

Why I am having "problem " tracking.

I should be doing an intercept during the SID. However, for track adjustments, I should be doing SMALL changes and not INTERCEPT.

That's why I am zig zagging and it will appear that I did not scan properly.

Can't wait for the next sortie to make the adjustments in my flying and hopefully, everything will come out good.

Till then ..
