25NL to 50NL jump advice

I'm pretty conservative with bankroll management, so IMO the very least you'd need at 50NL would be $2500 (50BI)... obviously the games get tougher as you move up, so it's good to have a bit of a buffer for the learning curve

Hey, you're doing nice, although thankfully you recognized it is a small sample (in reality, a very small sample 😀 ). My 2c, use a consistent BRM approach to move up and a set $ to move down, this is probably more important than WR. If you're good, your WR across all stakes will be decent. If you're not, it won't be decent, you will probably hit a wall and, assuming your motivation is good, you will look for resources, coaches etc and figure it out.

Conservative or aggressive to me has more to do with how much attention you want to constantly be giving to your bankroll, and how comfortably you are with this added level of stress, and lastly, your discipline. If you're disciplined and has no problem having to constatly check your roll to see if you need to move down, aggressive will make things faster for you. If you'd rather not have to check your roll every 5 minutes, go a bit safer. If you prefer to stay long stretches of time without looking at your results, and don't like stress, you have to go conservative.
