Gil-
You're not far off.  Since you did not specify whether the Ronchigram was 
inside or outside of focus, it's not easy to offer corrective advice, but, 
outside focus MOT and longer "w" strokes, inside focus TOT and longer W's.
Your images have different numbers of Ronchi lines. Less lines have more 
information so I would suggest a 4-line Ronchigram outside of focus. ( it's 
easier to see TDE with lines outside of focus)
