Yes, the truth is that it is not entirely accurate. There are at least two hours left to complete one day since I activated the investment (252.5 HIVE) and it has generated 0.2575 HIVE. Supposedly per day it should return me 0.613 HIVE approximately.

It is still early to draw conclusions, I will try to see when it generated in a whole week.

However, by doing the calculations with a calculator, it fits with what you are generating (I made ((amount * 44%) / 12) / 30)). What is wrong is what the Binance interface expresses, which marks a higher number of estimated daily rewards.
