Greggs, Take it easy, Crunch Time, & Normal Play are part of enthusiasm which has nothing to do with impact on game shape whether you take it easy or crunch it. What impacts game shape is the number of minutes your players play in a week, you need to aim between 48-72 minutes with 60 minutes being the optimal amount of minutes a player should play in a week to gain the most out of game shape. game shape is something that factors from the prior week, so if a player has game shape of inept most likely he won't get to proficient which is the highest GS possible in a week. Also there is a random factor so sometimes your players will gain game shape even if you don't play 48-72 minutes and sometimes they even go down even if you get 48-72 minutes.
Also I looked at your team and I agree you got a good team, but even if your team could win the Canada Naismith the rules apply to your like anyone else you promote to the above division and not more. Don't think I'm dissing your team if anything its much more than I can say for most teams in your situation, right now your team looks like a 2nd,3rd seed in division 3 just a notch below being good enough to promote to div 2. I was exactly in the same boat as you my first season where I went undefeated
