Nope, nothing has changed in the profit payouts code. There are 2 reasons for lower profit:
- STEEM price dropped - this makes @tipu vote value lower so the income is also lower and this is a 1:1 ratio. If STEEM price drops by 50%, so does the profit.
- there is a slight variation in payouts and its kinda hard to explain but lets try :) Lets say that @tipu voting starts at 8:00 each day and your profit is paid at 10:00. If only few users will buy votes until 10:00 - then most of the income will be generated after 10:00 and it will be paid in tomorrows payout - not today. So payouts each day may differ a little, depending on when most of the profit was generated. The bottom line is that no profit is lost, it just larger part might be paid today or tomorrow.
