- Straight Rail Ladder Specifics
- Challenge Matches
Except as noted (or contradicted) below, the General Ladder Rules and Regulations
will apply to this ladder.
The handicapping for this ladder is based on the number of points a
player scores per inning (over his last five games). Stroke by
stroke score keeping will be used to get these numbers and allow some
statistics about the matches and player's performance.
Straight Rail Ladder Specifics
- A copy of the Billy Aardd's Club
Carom Billiards rules will be in the magazine rack by the
attendant's counter. They, the Billy Aardd's Club
General Rules of Carom Billiards , and the Tournament Rules and
Regulations , will apply except where indicated otherwise.
- Each match will be consist of one, equal innings, game of 45
innings or 100 points. The handicap will have one player
starting closer to final game score than the other (who will
start at zero). The winner of the match will be the
person finishing closest to (or exceeding the most) 100% of the
points they needed to get for the win. (e.g. 32/40 beats 78/100)
- In matters pertaining to the Ladder (argument of fouls,
clarification of rules, etc.), the Ladder Director's (LD)
decision will be final.
- Each player must pay for their share of the table time (based on
the current league-rate).
If you've not played on the ladder before, or if it's been a long time
and you'd like to establish a new PPI, you will need to shoot a
qualifying game of 20-innings. If any five inning stretch (of
innings 1-5, 6-10, 11-15, or 16-20) is blank then shoot another five
innings (only once).
Handicaps for the matches are based on a player's performance over their
last five matches. Their performance is measured as the number of
points made each time at the table (points-per-inning, PPI).
For calculation of initial scores a minimum PPI of 0.150 will be used.
Each match should take no more than about an hour (there is no time
Here is an example of how to determine each player's starting score for
The formula for finding the starting score is:
100 - Ceiling (PPI * 53)
| Example: Starting scores
|| Starting |
| A. Low
| B. High
Starting with round 42 the above formula was based on 53 innings instead
of 45. The games are still limited to 45 innings though.
- If a challenge match is arranged and then can not be played it
will be ignored (as if it was never arranged). Challenge
matches will never become an IMMEDIATE forfeit. Though
after play has started they can be become an INPLAY forfeit.
- Challenge positions, used in challenge matches, are earned when a
player shoots at least ten percent over his LBPI for the round
and wins his scheduled (regular or odd) match (challenge
positions can not be earned from the play of a challenge match).
Each ten percent shot over a player's rated LBPI will earn
him one challenge position in the next round.
As an example, if Ed shoots 1.57% of his rated LBPI in a round
then in the next round he will be awarded five challenge
- The challenge handicap depends on the number of positions
challenged and will decrease the LBPI of the challenged
player to a fraction of normal for the challenge match.
The fraction is 0.90 for 1 position, 0.85 for 2 positions, 0.80
for 3, etc. The minimum allowable fraction is 0.05 (18
positions). The challenge handicap is generated by the
players of the match. The LBPI of the challenged
player is multiplied by the fraction and then a modified handicap
is calculated using the handicap formula above.
No more than 10 innings will be recorded per line.
