FAQ

Can I Predict the Turnip Price on My Island?

Generally, you cannot use this to predict turnip prices because you don't have the seed. However, since seed is a unsigned 32-bit integer, we can enumerate all possibility. On my computer, it takes 16 minutes to enumerate all combination of patterns and seeds on a single thread. Besides, even if you have the seed. This calculator won't work the first time you buy the turnips, according to @_Ninji's reply.

One thing that can skew it for reports: the FirstKabuPattern flag (set directly after the first day you buy turnips on your own island - i.e. not travelling) forces pattern 3 and generates a new buy price.
