Injection Quantity - have I got this right?

A have I got this right question here.

Group 001: Injection Quantity

  819 /min  Engine Speed (G28)

  6.9 mg/str  Injection Quantity 

  7.7°KW  Injection Duration (specified)

  62.1°C  Coolant Temperature (G62)

Group 013: Idle Stabilization (Injection Quantity Deviation)

  -0.33 mg/str  Injection Quantity Deviation Cyl. 1

  -0.19 mg/str  Injection Quantity Deviation Cyl. 2

  0.19 mg/str  Injection Quantity Deviation Cyl. 3

  0.35 mg/str  Injection Quantity Deviation Cyl. 4

I am assuming that the 6.9 mg/str is an average across all four cylinders so

Cyl. 1         6.9-0.33  =  6.57 mg/str  Injection Quantity

Cyl. 2         6.9-0.19  =  6.71 mg/str  Injection Quantity

Cyl. 3         6.9+0.19 =  7.09 mg/str  Injection Quantity

Cyl. 4         6.9+0.35 =  7.25 mg/str  Injection Quantity

But have I got this right?

Thanks
