it's technically a bit late bc I got distracted by dxpw, but official beach xp gains
Start: 113,799,596
End: 119,316,463
Gains: 5,516,867
note that I missed far to many happy hours, had a few days where I didn't use up all my ice cream, and didn't no-life weekends. Beach doesn't give much per tick, but it adds up and is free (I got roughly 110 per most of the time)
