Wilks was retired for a reason: it favored heavier lifters. See both scores and exactly where you stand today.
For two decades the Wilks coefficient decided "best lifter" awards — until the IPF retired it in 2019 after analyses showed it systematically favored heavier body weights. DOTS (and IPF GL points) replaced it. Lifters with old meet results still need Wilks to compare eras, and anyone arguing about all-time totals needs both. This calculator runs the original Wilks polynomial and the current DOTS polynomial on the same lifts, shows the gap, and computes the total you need for the next DOTS milestone.
Powerlifters comparing across eras use it because old meet results are in Wilks and current ones are in DOTS — and the gap between the two scores reveals exactly whether the retired formula was flattering their weight class.
On the DOTS scale: under 200 beginner, 300 intermediate-adjacent, 400 advanced (roughly national-meet qualification territory), 500+ international class. A 220 lb male totaling 1,315 lb scores about 365 Wilks and 369 DOTS — solidly intermediate. The scales track closely at middle body weights and diverge at the extremes.
Statistical bias. Validation studies on modern meet data showed Wilks gave heavier lifters an edge — two lifters with proportionally equal performances got different Wilks scores depending on body weight. DOTS (2019) and IPF GL points were refit on hundreds of thousands of current results to fix the weight-class skew. If your Wilks is higher than your DOTS, the old system was flattering your class.
It depends on body weight, which is the point of the coefficient. The calculator inverts the polynomial: at 220 lb body weight, going from 369 to 400 DOTS takes roughly +110 lb of total — but at 165 lb the same jump takes far less. Lightweight lifters gain points faster per pound added; heavyweight lifters need bigger totals for the same score.
