Additional analysis, after the 2014 Marine Corps Marathon results shows that the Boston Marathon cutoff trend is now at BQ minus 68 seconds.

The MCM marathon had considerably less entrants this year than last year. This resulted in fewer people meeting the minimum Boston Qualifying Standard. On top of that, a lower percentage of runners met the standard at the 2014 run versus the 2013 run.

Notes:
BQ2014 = Participants who met the BQ Standard for 2014, which was BQ Standard minus 1 minute 02 seconds.

The BQ cutoff can be predicted by looking at the total number of people who raced in 2013 autumn races and met the cutoff for the 2015 race (called BQ2014 in the tables above - 2014 being the application year), and projecting a cutoff for the 2016  race so that the same number of people qualify.

More simply put, last year at this time, 8871 people were 1m02s under the BQ Standard to meet the BQ cutoff for the 2015 race; how much time difference would be required to ensure 8871 people from this year's events would qualify for the 2016 race?

The answer is 1 minute and 8 seconds. This represents the current cutoff - assuming the trends observed in these feeder 10 marathons hold true for all Boston Qualifying marathons.

Using a cutoff of 1 minute 8 seconds, 8872 people would qualify for the Boston Marathon based on their 2014 race results. This is approximately equal  to the 8871 people who qualified for the Boston Marathon based on the same race results for the 2013 year.

This all assumes:
1) People's motivation for applying to the Boston Marathon remains the same for the 2015 and 2016 races .
2) The proportion of applicants from the feeder races remains the same for the 2015 and 2016 Boston Marathon remains the same.
3) The allocation of General Entry slots for the 2015 and 2016 Boston Marathon remains the same.
