Rather than improving your B and C game, why don't we just play A game all the time? 
I wanted to come back to you on this Mark as I think some further explanation may help you to understand what Jared means when he talks about Inchworm - here is my intepretation.
The concept of an A game, B game, and C game is built around a bell curve shape. At the front-end is your A game and at the rear-end
your C game. Everything in-between is your B game. (A bell curve looks a little like a D laid on its wide with the two ends tapered.
What is your A game now, will become your B game later, as you learn and improve. It is likely that you only play your A game a small percentage of the time and your C game, hopefully, too. The rest is your B game.
Because new information has to go through the four stages of learning I described earlier under the Adult Learning Model, it is only when new information is learned to either Concious Competence or Unconcious Competence that you can include it in your A game, and also your B game. If you are Unconciously Incompetent (your not even aware of a strategy - let"s say set-mining - then it is not in your game at all so will autmatically form part of your C game as you are just playing pocket pairs poorly mostly and only ocassionaly by luck playing them better). Once someone tells you about set-mining or you figure it out yourself you become Conciously Incompetent until you start to understand the whys and wherefores of how to do it.
Back to A Game - you go and watch a video/read a strategy article or just become aware of 3-betting and 4-betting (you are new to poker and only know about limping, raising, and calling raises pre-flop) but you have not mastered how it works, why, when to pull the trigger and when not to, etc. It takes time to work this into your game and to become proficient at it. You might start with 3-betting and 4-betting in position 100% of the time, and the refine your strategy from there, or you may only 3-bet your value range and not understand when to bluff or semi-bluff. You might stick to some "rules" you learnt from the strategy you read/watched. This new information when applied correctly pushes your play into - A game, but as it is all new most of the time you are making some good moves and some mistakes - B game, and sometimes you apply it poorly and just get all confused when to and when not to - C game. Eventually, you get so good at it your A game now includes this new strategy and you mostly get it right. So, you cannot always play your A game, or even 80% of the time, as new concepts take time to become proficient at.
Your old A game, with no 3-betting or 4-betting in it as you didn"t know about them (you were Unconciously Incompetent), is now your B game or even C game. In your new A game you instincitively know how to react so you 3-bet bluff those high VPIP players and pick up lots of uncontested pots, you start flatting medium strength hands against opening ranges you dominate, and you 3-bet for value only when those rocks open (you are now Concsiously Competent and becoming Unconciously Competent as it becomes instinctive). But now you start to learn about targetting weak players and how to deal with them. You learn about different player types, how to isolate, and which players you can value bet to death, when players will not give up and you have to give up the bluff you are running, etc. (a new skill that you have become aware of so Conciously Incompetent, but have just started to learn about hoping to become Concisously Competent and then Unconciously Competent) This new skill is added to your game but you are very new to it so your A game now includes this but you don"t do it well very often so you play only your B game most of the time again. Occasionally, you make a mess of it and you get distracted by applying new skills and your 3-betting and 4-betting suffers so you play your C game sometimes.
Also, you game is suffering as you make some mistakes set-mining and sometimes flat in position when you could raise and sometimes set-mine when it is not profitable due to effective stack sizes. If you do not work on this mistake and concentrate instead on learning more new strategies the gap between your A game and C game gets wider - so you work on the poor parts of your current game as well as adding new skills.
Imagine charting all your poker skills - there are some that you do very well, some you do well most of the time but sometimes you get spot on and other times make a mess of, and there are other parts of your game that you are very poor at - A game, B Game, and C game. Everytime you learn something new you moved your A Game forward (stretching the front end of the bell curve) but your C game stays rooted until you improve those mistakes. Everything inbetween is your B game.
