Not sure why that happened but I noticed that too. Perhaps there was money pulled out of the some of the other Farms.
Or maybe it has to do with the drop in price, if the price goes down in USD, the amount of CUB produced provides a greater return.
I am not sure how it happened although not complaining.

I checked some of my old screenshots. They changed the multiplier from 10X to 15X. Earnings have only increased ~40% during the last two weeks. If it wasn't for this change, the APR would have gone much lower. It's really clever what @leofinance did. My post on this will be published soon.
