Usage depleted overnight. All updates set during free time.

Just completed my approximate one hour test of using the internet with only this computer connected directly to the modem.  I spent about 25 minutes signing enrolling in our healthcare plan and then surfing...pintrest, facebook, foxnews, cnn, aol, yahoo, checked email...etc... the first 45 minutes it stayed at 44% and then dropped to 38 over the next 15 minutes.  As you will see on my screen shots I am including my hughesnet meter and my glasswire meter.  In the second shot they seem to have caught up with each other.
