criterion was 4 minutes and 59 seconds until the LIRR changed it because of a bug in their computer systems. Critics believe the OTP measure does not reflect what commuters experience on a daily basis. The LIRR publishes the current OTP in a monthly booklet called TrainTalk. TrainTalk was previously known as "Keeping Track." A more accurate way to measure delays and OTP has been proposed. Called the "Passenger Hours Delayed" index it can measure total person-hours of a specific delay. This would be useful in comparing performance of specific days or incidents, day-to-day (or week-to-week) periods, but has not been adopted. Ridership has increased from 81 million passengers in 2011 to 89.3 million passengers in 2016, which is the railroad's highest ridership since 1949. The all-time highest ridership was in 1929, when 119 million passengers rode 1.89 billion passenger miles. This increase in ridership has been attributed to the increased usage of the LIRR by millennials, and the increase of reverse-peak travel. Pension and disability fraud scandal A New York Times investigation in 2008 showed that 25% of LIRR employees who had retired since 2000 filed for disability payments from the federal Railroad Retirement Board and 97% of them were approved to receive disability pension. The total collected was more than $250,000,000 over eight years. As a result, Railroad Retirement agents from Chicago inspected the Long Island office of the Railroad Retirement Board on September 23, 2008. New York Governor David Paterson issued a statement calling for Congress to conduct a full review of the board's mission and daily activities. Officials at the board's headquarters responded to the investigation stating that all occupational disability annuities were issued in accordance with applicable laws. On November 17, 2008, a former LIRR pension manager was arrested and charged with official misconduct for performing outside work without permission. However, these charges were all dismissed for "no merit" by Supreme Court Judge Kase on December 11, 2009 on the grounds that the prosecution had misled the grand jury in the indictment. A report produced in September 2009 by the Government Accountability Office stated that the rate at which retirees were rewarded disability claims was above the norm for the industry in general and indicated "troubling" practices that may indicate fraud, such as the use of a very small group of physicians in making diagnoses. Another series of arrests on October 27, 2011 included two
