I have tried to be very patient with you. I know that it's a terrible thing to only win 10 grand when you would prefer 79 grand--but I can't rewrite the rules for you.
You will obviously never be satisfied with any answer that you get until you get your $79,000. Trust me though--it is just not going to happen.
The prizes for each combination of winning ticket are clearly established in paragraph 7.3.1 of the rules.
The PRIZE FUND is the amount of money available to pay prizes in the given category. Available does not mean guaranteed to be paid. The amount of money in the prize fund is based on the amount of money from the gross sales of the tickets. The amount of money in the prize fund, for any given game, is approximately 50% of the gross sales.
Read the following rule very carefully:
2.16 Prize Fund - That portion of MEGA MILLIONS gross sales set aside for the payment of prizes. The Prize Fund for any drawing is expected to be 50% of sales, but may be higher or lower based upon the number of winners at each prize level, as well as the funding required to meet the advertised jackpot.
In answer to your final question, "Where does it state the circumstances under which the percentage payout will occur?", the simple fact is that the rules don't state that answer. Obviously, if there are enough winners in the given category of prize winners, the portion of the prize fund alloted to that category will be used up.
Think about it this way. What if you were the only person in the world that happened to get 4 plus the mega number?? Do you really believe that would then entitle you to collect 3.5 million dollars? Because under given your thinking, that is exactly what you would expect. Better yet, if you were the only person who got no numbers other than the mega number, do you really think that you would win 5.34% of the total Prize Fund for that game, or in your case $6,514,800.00---seriously--for getting just 1 number right?
Look, the prize fund is simply a fund from which prizes are paid. Nowhere in the rules does it say that the prize fund will be completely depleted each game.
I'm happy for you that you won 10 grand. That's great. But that is all you won.
