#ArizonaBTCReserve ROI = USDT Earnings / (100 USDT + Opening Account Balance + Modified Deposit Amount in the Selected Time Interval)

Modified Deposit = Deposit * (Time Between Deposit and End Date of the Selected Time Interval, in Seconds) / Total Time of the Selected Interval (in Seconds)

For example: if the selected interval is daily, the denominator is 86,400 seconds (24 hours), and the numerator starts from 86,400 (remaining time) and goes down to 0.

When the selected time interval starts, the deposit weight = total deposit amount. After 12 hours, weight = 50%; after 23 hours, weight = 1/24.*
