Hi adelaar,
It sounds really good. Using charts is seem reasonable while starting out.
About calculating outs, i think it concept where you just learn with experience and more you play and calculate your outs easier it get. I don't have hear any alternative to calculating outs then just doing it and with time it become almost automatic.
If you really struggling with pot odds/calculating outs during play search Google "poker outs calculator" and look up good one that you can use during play, i believe all poker rooms allow use theses softwares. Also most of them have good "get it free" promotions if software is no free.
I am only in 1/3 of book, i am taking my time with book and taking lot notes and no try fast read but really learn, but it more about where people make mistakes by having too much folding frequencies or calling frequencies.
For example if we open preflop and player call lot more hands then need preflop and fold flop when he miss it.
So he no continue enough frequent on flop and we print money betting 1/2 pot almost any board whatever hand we have.
This is very simple example but book is about making you thinking less about ranges/odds/board textures and more about frequencies. How we can keep our frequencies closest to correct and by reading hands/adjusting to very incorrect frequencies win money from other players and where people make most mistakes by folding/calling too frequent.
For example most regular players continue on turn/river not that frequent after making standard cbet very frequent and if you know they have big gap between they flop cbet and turn bet % you no really need know your hand IP to just print money from him on good boards by calling flop any hand and betting turn after they check huge % times.
If you are not that confident in your hand reading skills you might be interested read first How To Read Hands At No-Limit Hold'em by ed miller
Book i am reading have concepts what is very easy to interpret incorrectly on lower stakes by misunderstanding them(super important) so i recommend read it sometime later when you feel more confident in your understanding about outs/odds/boards/hand strengths/hand reading or if you feel confident enough now sometime sooner, whatever book you choose to read now take your time with book and no fast read it and you can discuss topics what is unclear or interesting with me or someone else here at forum if you have need/want it.
