Cash game leaderboard on ggpoker

At plo25 there is a player finishing first or top 3, every single day. I played on ggpoker for around a month and a half. The best I finished was 7 I think after playing a very long session and multi tabling a bunch of tables. I was dead tired the next day and borderline depressed. I’m not a young men anymore and can understand some people have more endurance but still.

Usage of any type of tracker or software is illegal on ggpoker from what I understand. How possible for a human being is it to finish 1st everyday for a very long period of time? It must take a tole on your health mentally and physically ? For the big time grinders out there who are familiar with ggpoker, for how long and how many tables on average per day do you need to play to finish first? Thank you
