Ladder Rules and Regulations
How the ranking system works:
Rankings
can change if a lower-ranked (RankLow) player beats a higher-ranked (RankHigh)
individual:
- Winner becomes ranked: (RankLow
+ RankHigh) / 2 – 1
- Loser becomes ranked:
(RankLow + RankHigh) / 2 (round up when quotient is #.5).
- Everyone originally ranked
between RankHigh + 1 and (RankLow + RankHigh) / 2 – 1 moves up one
position
- Everyone originally ranked
between RankLow – 1 and (RankLow + RankHigh) / 2 moves down one position

Rankings
change on a first-come first-serve basis: i.e. we change rankings first based
on matches that finish first. As an
example, suppose at the beginning of a night, three matches are to take place:
A vs. G, C vs. H, B vs. F, and assume that all lower ranked individuals win,
and they finish in that order, then:
|
Rank |
1 |
2 |
3 |
4 |
5 |
6 |
7 |
8 |
9 |
10 |

In other
words, successive changes would be based on previous and immediate changes in
rankings, not on the original order at the beginning of the practice.
Limitations, caveats, and other information:
- Students only (undergraduate
and graduate) are allowed to participate
- A maximum of 1 ladder match per practice per person
is allowed
- Players may challenge others
through E-mail or at practice
- A challenged player must accept the invitation (be moved to the
bottom of the list if he/she refuses), unless he/she can’t be at practice
- A player that wins 3 matches
(1 week’s worth) in a row against lower-ranked players is automatically
bumped up one rank
- A player that doesn’t play a
ladder match for three weeks (9 practices) is automatically moved to the bottom of the ladder
- Players may only challenge those that are within 5 ranks above them,
unless those players are not at practice; they then can challenge the next
nearest rank above them that has not already played a ladder match
- Club members are by no means required to participate
in the ladder
– in fact, players may play with ladder participants as often as they
possibly can during practices; however, we encourage all student members
to participate – it’s a great way to challenge your friends while having
tons of fun!
- Please be aware that your rank can change substantially
even if you don’t play a match for a couple of weeks! As you can see in the previous example,
player E did not play any matches, yet started at rank 5 at the beginning
of the night, but ended up at rank 8 at the end. Player D also slid 3 ranks by not
playing. On the other hand, it is
possible to move up on the ladder without playing as well!
- Members not on the ladder may enter at any time – however,
they are added to the bottom of the ladder.
- For a ladder match to be
counted as official, each player must sign their names on a score sheet,
write their finish time, and fill in all appropriate scoring information.
- Prizes shall be awarded for
those that fare well in the ladder system!
Match Instructions
- Matches are best of 5 games
(first to win 3 games)
- Each game is to 11 points
- Serve changes every 2 points
- 10-10 ties should be played
until one player wins by 2 points (i.e. 14-12)
- Serve changes every 1 point
if and when 10-10 occurs
Score Sheet Instructions:
- Names -> Print players’ names
- G1 etc. -> Print point totals per
player for each game
- Winner [x] -> Mark X to denote
winning player
- Date -> Print date match was
played
- Time Finished -> Print time at which
match was finished
- Signatures -> Player signatures
