I entered Weights for several dates in the Tests sections. However, when viewing the Weight Chart, accessed from the Home page, the wrong dates are recorded. For example, I entered a weight of 170 lb for Sept 20, but the Chart showed the date as Sept 18.
I am using a downloaded demo of the program and I like it very much so far. However, if the charts do not provide accurate information, I would certainly reconsider purchasing the product.
