The spreadsheet was a necessity after I realized I needed to keep track of the dailies and the singles that disqualify you if you enter more than once. I've been sweeping for exactly 2 years now, having stumbled upon this forum in July 2013 and have almost 3200 entries in my spreadsheet now, and that's including two 4-month-long breaks when I was simply too busy to sweep. So basically 200 sweepstakes per month that I've been active!
