It is really messed up, there are so many names for different accomplishments, but this one that I found is someohow most apropriate.
Have you ever herd about boxed set ?
"Winning the four majors in consecutive tournaments but not in the same year is known as a Non-Calendar Year Grand Slam, while winning all four majors at any point during the course of a career is known as a Career Grand Slam. Winning the gold medal at the Summer Olympic Games in addition to the four majors in a one calendar year is known as a "Golden Grand Slam" or more commonly the "Golden Slam". Also, winning the Year-End Championship (known as ATP World Tour Finals for men's singles and doubles disciplines, and WTA Tour Championships for both women's disciplines) in the same period is known as a "Super Slam". Together, all four Majors in all three disciplines (singles, doubles, and mixed doubles) are called a "boxed set" of Grand Slam titles."
As I've heard, don't take me on this seriously, in this topic
http://tt.tennis-warehouse.com/inde...nd-slam-a-future-normal.565509/#post-10384604 it was discussed how CGS will become something normal. So I thought why stopping there ?
I've explained above my thoughts about that. But, just imagine if Novak takes Super Slam, don't you think there would be some immediate changes like introducing very fast surface in one of slams ?
