TOTAL score calc

Can someone please explain to me how the scoring on this game works. I understand the Base Score depends on how many units/buildings you kill and the Bonus Score depends on how many units you lost compared to how many built… blah blah blah.

I am wondering how the Total Score is calculated. I thought it was the Base Score multiplied by the Bonus Score. But I just played a game where my Base Score = 217 and my Bonus Score = 2.56X. It says my Total Score = 452. If Total Score was Base Score multiplied by Bonus Score it would be 555. Everyone else in the game has a Total Score equal to the Base Score times the Bonus Score.

I’m so confused.

There’s not much variation. It may be that you have the wrong base score.
