As I wanted a more neutral perspective on the idea of The Greatest of All Time than the usual MTF banter, I have designed a mathematical system that takes into account the most popular statistics in order to create my very own trademarked-but-not-necessarily-so-original Slasher's Greatest of all Time list. Now, this is a bit different to
's hard-worked list in a sense that I try to create a point system for every stat that can be used.
ATTENTION: This thread needs to be used only for talking about this list. I know, I know, but it's not about praising me, please use constructive criticism and make plausible suggestions (stat additions are no longer accepted). Obviously let me know about mistakes, cause there's bound to be some. But if you want to talk about your idea on the whole GOAT subject, please find this thread: http://www.menstennisforums.com/2-ge...~-vol-3-a.html
The list has the following entry allowance:
- Player has at least one Grand Slam semifinal (only those including and after Wimbledon 1924), final or title (all time), or has won a Pro Slam or got a Pro Slam final.
- Player has been number 1 for at least one week, or noted at least once in the world number 1 pre-open era lists.
- Player has won an open era Masters title.
- Player has won the Olympics [post 1900] or gained a silver medal or who won the Year End Championships [open era] at least once.
The most important stats refer to Majors titles, streaks and records, world number 1, or defeating other Grand Slam champions (or Pro Tours for pre-open era players). The 5 directions of the list are noted above: PERFORMANCE, DOMINATION, LEADER, EFFICIENCY and CAREER. Here they are:
- Grand Slam titles
- Grand Slam finals
- Grand Slam semifinals
- Pro Slam titles
- Pro Slam finals
- Pro Slam semifinals
- Major venue title streak addend - this calculates a total of points based on Grand Slams won at the same venue in consecutive years: streaks are ponderated with x^2.05, where x is the number of slams won in consecutive years inside the streak. Number of streaks for each x is also memorized, but the columns are hidden. The total sum is then divided by 3 to decrease its impact in relation to the Grand Slam streak.
- Surface variation - for this stat the total number of Majors per surface are counted, the highest value on a given surface is used to extract the percentage of Majors on that surface, along with the lowest value and surface count. (1 / (Bst/Wst)) x 15*(Surf Cnt-1.95). The details for this addend are also hidden in the table.
- Grand Slam streak addend - this calculates a total of points based on consecutive Grand Slams won: streaks are ponderated with x^2.05, where x is the number of consecutive slams inside the streak. Number of streaks for each x is also memorized, but the columns are hidden.
- Pro Slam streak addend - this calculates a total of points based on consecutive Pro Slams won: streaks are ponderated with x^1.55, where x is the number of consecutive slams inside the streak. Number of streaks for each x is also memorized, but the columns are hidden.
- All Slam streak addend - where a player switched from Amateur to Pro, they may have continued a Slam undefeated streak from Amateur to Pro Slam, for which this parameter is calculated by using the formula:
where x is the number of Grand Slams won consecutively before/after the switch and y is the number of Pro Slam won consecutively before/after the switch. The condition is that there should be no Slams missed before/after the switch.
- Weeks at number 1 (Open Era only)
- Maximum consecutive weeks at number 1 (Open Era only)
- Years at number 1 (pre-Open Era only)
- H2H against Top 10 Open Era Grand Slam champions while in the Top 10. The result of any match (victory or defeat) is taken into consideration only if the adversary of the current player was a Grand Slam champion at the time of the match, was a Top 10 player, and the current player was also a Top 10 player. This way, only the matches at the very top are counted. The zero point for this addend is 50%. This stat is only for Open Era matches, and only valid if a player has won at least one Grand Slam in the Open Era.
- Match record at Majors (both Grand Slams and Pro Slams are considered for the percentage). The zero point for this addend is 75%.
- Masters titles
- Important titles (important pre-open era tournaments are included here: World Hard Court Championships, World Covered Court Championships, Bristol Cup, etc.; WCT Finals are also included - after 1983 they value as half the weight; Grand Slam Cup wins are also included - they value as half the weight)
- Career titles (where known)
- Year End Championship titles (where available)
- Olympic medals (Gold, Silver and Bronze in singles)
- Pro Tours (this compensates the players before the Open Era who cannot have the Grand Slam H2H stat).
