* The price will reduce a maximum of 360 times in 90 days and will will fall to half its starting price.

You can't make it drop 360 times in 90 days and be at half ~ Either one or the other is an error.

Also it specfically says 14% on the patch notes.

The price of a plot of land is set to be reduced 14% every six hours.

This is copy and pasted.
