Is this even possible?

In all the times I've done tycoon racers (all of them), I have NEVER seen an account with such a low net worth, put that many points on the board so quickly. And I play on 4 different accounts (my main, backup, my bf’s, and his backup). On my main account, my net worth is 21,000. I had over 3,500 flags (accumulated between today and yesterday thanks to completing three gold sticker albums and completing two shelves in my show room) and I used the highest multiplier and had lucky rockets and hit doubles, et cetra. Still, I was only able to put up about 4,000 points. Yet they more than triple that in one hit. What multiplier could have been used with how many flags, that would grant 15,000 points in one spin?
