 November 5, 2010, 09:40 [Gambit] I have touble in grading. #1 New Member   sangbin park Join Date: Nov 2010 Location: south korea Posts: 8 Rep Power: 9 Hi I'm a first step in Fluent and gambit. I'm using [Gambit2.1.x:trainging Notes] to learn a gambit. But at the first step I could not understand about grading(dividing edge). In a book, grading has 8 option (succesive ratio,first length, last lenth, first last ratio,last first ratio, exponent, bi-exponent , bell shaped) but I just understand only succesive ratio..... please help me to understand rest of dividing option. and please recommend another good training book about gambit. my manual has a few explanation. thank you
