APF BEST LIFTER
FORMULA
PURPOSE:
Ever since primitive times, the argument has gone on: who's really stronger, the
heavy one lifting the big rock or the light one lifting the little rock? In the
old days of 'Weightlifting' the late Bob Hoffman originated a 'Hoffman Formula'
to determine whether or not a lighter lifter was better or not than a
heavyweight. When Powerlifting came of age, a set of bodyweight coefficients
came into use, where each lifter's bodyweight was assigned a coefficient. This
coefficient, multiplied by the lifter's total, gave a product number which
determined who was 'Best Lifter.
When APF was formed, Technical
Officer Greg Reshel issued a new set of bodyweight coefficients for both men and
women, and a set of charts for their usage was made. In 2004 Herb Glossbrenner
revised the formula coefficients for the APF-AAPF-AWPC and the usage is on the following pages.
MASTERS: When Powerlifting began having 'masters', it quickly became apparent that some sort of age allowance or 'handicap' was needed by this group to sort them out, one from another. How much better must a 40-yr-old be, than a 50-yr-old, to be considered a better lifter? How much better than a 55-yr-old, a 60-yr-old, etc? So, a set of age multipliers, or 'handicap numbers', was issued for Master Lifters year-by-year, from 40 through 80. Since then, however, the number of Master Lifters in the 50+ and 60+ group has become so large that a revision (based on extensive study and years of backup data) was needed. These new numbers are based on comparison of the totals of actual lifters over the past seven years, and a chart for their usage is on the final page of this section.
The formula is: (LT) times (GBC) = (PN)
LT - Lifter's Total
GBC – Glossbrenner Bodyweight Coefficient *
PN - Product Number
The Product Numbers of the lifters are compared and the lifter with the highest Product Number is 'Best Lifter.'
APF Master's Formula
The formula is: (LT) times (GBC) times (MAM)
= (PN)
LT - Lifter's Total
GBC - Glossbrenner Bodyweight Coefficient*
MAM - Masters' Age Multiple
PN - Product Number
*
For women lifters,
Glossbrenner Women's Coefficient ( GWC )
should be used.
The Product Numbers of
the lifters are compared and the lifter with the highest Product Number wins.
WPC MASTERS' FORMULA
* For women lifters, Glossbrenner Women's Coefficient should be used.
