To each his own. If you like this process, then stick with it, but I'm not sure I think this is a good approach. It looks like you're trying straddle the stakes ... like slowly dipping your foot in the water or something to make sure it's not too cold or shark invested

I briefly tried that method when I made my first jump from $2NL to $5NL and came to the conclusion that I was only doing it out of fear and that I had already, through bankroll management and beating my last stake, built a system through which I had no reason to play $2NL anymore and no valid reason to fear $5NL. I had 10 full buy-ins to "take a shot" at the next level. If I lost that many buy-ins, then I was clearly not ready for it and could drop down a level where I could clearly win back the money and try again another day. It's important to give yourself permission to fail through either coolers, bad beats, bad play, or whatever as long as you are trying to play @ your best. It's much worse to try to rise up and play scared money because you'll never be @ your best.

So, I would argue you're either ready for $50NL and should jump in full time with both feet or you're not and you should focus on $25NL. With this 1-2 hour a day method, you're putting $50NL on a pedestal and making the challenge larger than it should be both mentally and game wise with the subtle differences between each stakes as far as blinds, raise sizes, and villain tendencies. I've only been playing full time $50NL for a whole 3 days and it's taken me half-way through day 3 to realize that when a shortstack shoves allin for $10, that's the same number of big blinds as $5 @ $25NL - it seems like more @ $50NL. That example and so many other things add up, but by me focusing right now on one stake, I'll adjust better and faster.

The exception that I could see as being more acceptable is when you get to the higher stakes and the game selection just isn't there like @ $1000NL, $600NL, and maybe $400NL. As you move up more, there could be more situations where a really juicy $200NL table is twice as good as a tough, nit invested $400NL table. But, I'm pretty sure there's always a juicy enough selection of games @ $50NL to keep a capable, rolled player out of $25.

Anyway, just some food for thought - good luck with whatever you do.
