Thanks, It doesn't take all that much time to keep track of it if you organize some kind of personal tracking system which takes only a minute each day. It also gives an extra fun factor in the game (at least for me as I like to keep numbers on things).

I do see the numbers as a good selling point for new players in a way that people come to earn and stay for the actual game which is quite solid and fun. I also see a good chance that this 'pay-to-earn' model will become big in the gaming world similar to have 'free-to-play and 'pay-to-win' are currently the dominant earning models for devs. I hope you are able to convince your friend to try it out and I look forward to more people making these kinds of reports on their own results.

Good luck this season!
