BC 3.0.9b

BC 3.0.9b is a minor update that builds upon the data updates in 3.0.9a. Itincludes the following revisions:

  • The original activity list has been merged with the list from 3.0.9a, creating a longer, more broad list of activities.
  • Lean Dry Mass (LDM) and the associated average ranges were missing from the Averages Summary page in the software and in the overview on the first page of the "Big Table" formatted report.

And, from 3.0.9a:

  • Updated activity list to be more inclusive.
  • Revised meal plans to be more modern and include vegetarian and gluten-free options.
  • Updated the definitions page in the report.

NOTE: On Windows, you may continue seeing the old food and activity information after installing this update. If that happens, run the "Clear stale program data" utility found on the desktop and in the Start Menu folder. You will need to do this for every person that uses the BC program.
