There are several factors that go into calculating a weight for an athlete:
1. The global percentage regulator should probably be set at 90-100%
2. The daily % regulator (in yellow, if it is there, above every single work day)
3. The set and rep scheme %
4. The exercise % and alt max (When saving exercises, you must assign a % of an exercise to it. For example, it may say Bench Press 100% BP, to calculate from 100% of your bench press max. You may use Front Squat 80% BS to calculate a front squat max from 80% of your back squat max!)
5. The athletes training maxes.If you are having trouble getting the weight to appear, make sure all of these things are set how you want!
