Help!: Training Summary Weight Information Always Wrong

Can someone explain why the training summary at the top of the training calendar is nearly always wrong? Most notably, the weight min/max.

My weight has changed by at least 3 lbs. over the month of Feb., yet it always says that my min/max are the same, and it never changes as i select the box to save a new wieght to my profile. But IMO, that shouldnt matter. When you can enter a weight while logging your training, the program should be able to actually look at how your weight has changed over the month without saving to your profile. In other words, when i enter that my wieght is 180 on Feb 1st, then goes up to 183 on the 15th, but drops down to 181 at the end of the month, the training calendar should be able to track that as is says it should. My wieght min/max is not 183/183; its 180/183.

Many people run as a way to loose weight, it only seems appropriate that this site should effectively log your weight since it allows you to enter it for each activity, you can save it to your profile from there, and they have a competition to loose wieght that utilizes your training log to calculate wieght loss.

Thanks in advance
