You're right about that. The weight in the trainings table is not synced with the Withings weight data.
Why would you like to have that? Do you want to export the training data to Excel or other programs? Maybe you could sync the two tables using an Excel macro if you need it for importing to other programs.
Weight in training and weight in Withing inconsistent
My Withngs weight is synchronised with run.gps and it's OK : the data is showed in MyRun.GPS-->MyBodyWeight.
But, in the training list, the weight is not correct. It correspond to the weight entered manualy on the application rungps on my smartphone. How can I do to synchronise my weight in a training with the weight from my Withings ? (I do all this documentation : http://www.gps-sport.net/dialogs/bodyWeight/settings.jsp).
