How Long?

This topic has a dual meaning.  Firstly, approximitly how long are l -> r and k -> g?  I'm guessing that it really varies depending on how fast your writing, but I'm not sure how long those should actually be.  Secondly, I'm wondering how long it took you to obtain a fluency in gregg where you could take notes when an average person speaks?  I'd think it would be about a year, but I'm just curious.  Thank!
