I did the same test as Harboe. He's right, the combat log is wrong but the visual numbers are right.
Here at this video, start from 0:30, you will see the Chanter mentioning her HP at the start and after doing so.

Full HP: 13499
HP after fight: 8560
Damage dealt according to the LOG:
3487 Kinetic Slam
1017 + 1017 Steam rush
Auto Attack 272
When I subtract all the damage according to the log the HP is 7706.
Damage dealt according to the visuals:
3487 Kinetic Slam
1017 + 163 Steam rush (163 was the visual number)
Auto Attack 272
When I subtract all the damage according to the visual number at Steam Rush the HP is 8560.
#Was solved by Harboe already, but yet I don't understand the formula for calculating the 2nd damage, maybe he can get around it.
