I have 4,000TT and recently sat down and finally input all of it into my electronic logbook. Granted, I had 300 hrs already put into the eLog it took me a week and a half to complete. Spent roughly 3-4 hours a day on it though. Looked at it as an investment. Glad I did because I was able to really tidy up all my app. I have a MTC in March. Very excited!
