Apple Logic Pro /LogicExpress Discussion

I know this question would be relative to the time one puts in, and
the comprehension of working with a non linear format. As I am both
willing to devote the time, have had my own facility and have been in
business for 30 years now, (the last 16 working with DAW's), I am now
contemplating going with Logic. 

So the question I would like to put forward is... what in your
opinion(s) would be an average time to be comfortable in executing
Logic Pro. I have heard that 30 days of profanity should do it.


Thanks,
