Equation for the top 5 marketeers' prizes
If what you got was an item on your alt account, and the qi is say 10k, do you just lose out on the item?
You will be able to send them to your main account (only if your main has the appropriate qi to hold the items. Otherwise people would keep high qi items in their account just so they can get no-qi items on their main account.)
They don't receive TC equal to the equation + original profits though. The equation factors in their profits. The only thing the equation does is it splits up a bonus prize pool which is determined by how many people participated in the event among the participants. Nobody's going to be getting millions extra. With the current number of participants (54), that's 540k being split up among the top 5 people, which gives them an average of 108k plus however much they made on their own.
Also, if you think about the formula for top 5 players' profit not in terms of the ratio to the pool, but in comparison to your own profit during the event (which is x), you will get:
x(2 + zn/y) = 2x + xzn/y , which means that each of the top 5 players gets at least double of what he's earned plus (xzn/y) plus items (note that here their profits are already included to the formula).
