I am way beyond sticking to a specific amount, When I first started to build a Bankroll, I stuck to a 1% rule but my Bankroll has grown so much I don't worry about it, I have well over $600 Dollars in it and I still buy-in for $1 Dollar, Why? because I am not Interested in making Money!
Poker is much more than a means of making Money, For me it is a way of having a little Fun, whenever I feel in the Mood for a Game. We don't all play just to make a 2nd income, That would be too much like Hard work, and at 68 I gave up work and retired over 10 years ago. so starting again is not on my "Bucket List".
Playing just for the enjoyment the game gives me is not a crime, nor am I wasting time on playing below my Limits, I am a Hobby Player playing Purely for Fun and the Fun cost's me nothing!
When the Fun Stop's, STOP!
I Will!
