DOTS relative rating

The DOTS relative rating is a point rating for powerlifting and its individual disciplines. It compares strength performance based on gender and body weight. The DOTS formulas allow a coefficient to be determined by specifying the body weight, which multiplied by the performance provided results in a DOTS point value that is comparable to that of other athletes.

Name and introduction

According to the author Tim Konertz, DOTS stands for "Dynamic Objective Team Scoring System".

The model for the development of the new rating was the Wilks coefficient used by the International Powerlifting Federation (IPF) and various national offshoots until the end of 2018 . This coefficient-based relative evaluation, developed in the 1990s, has shown various shortcomings since the introduction of classic powerlifting and the associated popularization of the sport. In particular, the preference given to particularly heavy male athletes was often criticized.

After replacing the Wilks coefficient in the IPF with the "IPF points" introduced in 2019, the Federal Association of German Powerlifters (BVDK) decided to adopt the DOTS relative rating for team competitions such as the powerlifting Bundesliga from 2020, as the IPF points are not are suitable for team ratings. The first competition in which the DOTS relative rating was used was the Insanity Meet 2019 , the largest non-association powerlifting event in Germany.

At the federal committee meeting of the BVDK at the end of 2019, it was finally decided to use DOTS for individual competitions from 2020. Furthermore, the Swiss association Swiss Powerlifting has also decided to use DOTS for the determination of the best athlete and the club evaluation from 2020 DOTS.

calculation

Formula for men

${\ displaystyle DOTS coefficient (w) = {\ frac {500} {- 0.0000010930w ^ {4} + 0.0007391293w ^ {3} -0.1918759221w ^ {2} + 24.0900756w-307.75076} }}$

For w , the body weight of the athlete is to be used. The definition range for men has been restricted by the author from 40 kg to 210 kg.

In table calculation form: DOTS coefficient = 500 / (- 0.0000010930 * w ^ 4 + 0.0007391293 * w ^ 3-0.1918759221 * w ^ 2 + 24.0900756 * w-307.75076)

Formula for women

${\ displaystyle DOTS coefficient (w) = {\ frac {500} {- 0.0000010706w ^ {4} + 0.0005158568w ^ {3} -0.1126655495w ^ {2} + 13.6175032w-57.96288} }}$

For w the body weight of the athlete is to be used. The definition range for women has been limited by the author from 40 kg to 150 kg.

In table calculation form: DOTS coefficient = 500 / (- 0.0000010706 * w ^ 4 + 0.0005158568 * w ^ 3-0.1126655495 * w ^ 2 + 13.6175032 * w-57.96288)

example

In a bench press competition , three athletes achieve the following performances and results:

Surname	Body weight (kg)	pressed weight (kg)	DOTS points
Athlete 1	74	100	72.365
Athlete 2	93	115	73.169
Athlete 3	120	125	71.788

While Athlete 3 moves the most weight, he has the fewest points for performance in relation to his body weight. In the relative ranking, athlete 2 wins with a body weight of 93 kg.
