Let me be clear: I don't care about Magnitude 6. In fact I am actively against increasing magnitude, as such brings us closer to Game Over.
You may consider sitting in place being a Growth Maximiser until the end game score screen pops up to be a victory worth achieving. I do not. I would consider such to be both a failure and a waste. I want to explore the setting that Raising Kittens has created. Investigate strange places and meet interesting creatures. (To adopt / befriend / kill / eat as appropriate.) Build a story with our actions.
Your plans in no way help with this. It will always be more 'efficient' to put focuses on investing in more growth that we can then use to get more magnitudes that can in turn be used to generate more growth. With each turn making it harder and harder to justify using focuses for anything else.
You had a plan to rush Magnitude 4 in the shortest possible time. Now you have a plan to rush Magnitude 6 in the shortest possible time. And no doubt when it is complete you will be ready with a new plan to rush Magnitude 10 in the shortest possible time. Always insisting that whatever we actually want to do, the most efficient way to do it is to first generate more growth and more magnitudes.
I dispose your plans. Not because they aren't the best way of achieving the stated objective. But because I feel that objective makes the quest a worse experience.
