This is for tracking Fertile Money Tree patterns as explained in this YouTube video.
Some days you can bury more than 10k as the money tree, earning more money. Some people think there might be a pattern to it, and you can use this to track the pattern.
You can test each day by burying more than 10k, and if the resulting money tree gets you more than 30k, it is a "fertile" day.
Add days and mark them as fertile or normal , and the current prediction for the next week will be filled out. Anything that's unknown is assumed to be normal . Once you know your pattern, remove days back down to your pattern! The area below will predict the next week of days from the pattern.
Note: This has been disproved, there is no pattern. You can see here for more.
