Message from the Masters Chairman
To those holding a local meet and having a masters division: We don't expect you to have all of the age/bdwt divisions that we have in our masters meets, but there are age adjustment coefficients that you can use along with the Sinclair formula to make it fair to those masters taking part in your meet. Give as many awards to the masters as you want and tell them on your entry form the number of places.

To determine a lifter's "formula" total one multiplies his/her actual total by both the Sinclair coefficient and age coefficient.
Example: 44 year old male lifter, weighing 93.7 kg with a 225kg total
From the table (MF for Men):  Age 44 -> coefficient 1.189
From the Sinclair table (or formula) for a MALE: Body weight 93.7kg -> coefficient 1.142401
"formula" total = 225kg x 1.142401 x 1.189 = 305.621

Age factors for women (Huebner-Meltzer-Faber or HMF) were adopted by the IWF Master Congress of Nations in September in August 2019. Age factors for men (Meltzer-Faber or MF) were adopted in 2015. ​​
