Is this goal even realistically completable if you start off with 0 too pink ovens?
Is this goal even realistically completable if you start off with 0 too pink ovens?
Technically, yes. Despite how daunting some of the numbers can seem at first glance, the math shows that the goals are achievable. That said, it will definitely be more difficult for some than others for many reasons.
Whether you specifically will be able to finish this goal is something only you can know due to the wide range of factors involved. I think the most important of those factors to take into consideration (other than timing of real life vs. gaming) would be: do you have the coins available to buy enough ovens and serve all the required recipes, how many appliance slots do you have open and how many of the required parts did you already have in your inventory to help in building ovens faster.
In general, the sad truth is that the current goal models mean it's difficult (if not impossible) for newer players to complete all the tasks without insane effort or gems. Most choose to participate as far as they can while they work on building up their bakeries and its resources.
