Flow tested injector line from distributor, did 3 videos as illustration...

MB specs:
Idle Speed: 3cm^3/min
Partial Load: 30cm^3/min
Full Load: 100cm^3/min

My readings: (each water bottle 10g, so 10g has already been subtracted from each number)
Idle // Partial // Load(WOT)
1: 21g // 83g // 98g
2: 21g // 85g // 98g
3: 21g // 84g // 100g
4: 21g // 84g // 100g
5: 22g // 85g // 98g
6: 21g // 83g // 94g

EDIT: Videos:
Idle: http://www.youtube.com/watch?v=NyqTNyl99ZQ
Partial: http://www.youtube.com/watch?v=BWG4QWSsT2Q
Full: http://www.youtube.com/watch?v=uVQWB_LjYL8

Need help with converting....How can I convert since gasoline is not 1:1 grams to cm^3???
Density of gasoline is 0.68g/cm^3

EDIT2: Check my calculations here....but:
D=M/V
0.68g/cm^3 = 21g / V
...
V(0.68g/cm^3) = 21g
...
V = 21g/0.68g/cm^3)
V = 30cm^3
So that would give me:

Idle: 30cm^3
Partial: 125cm^3
Load: 147cm^3

So what exactly does that mean? Am I running heavily rich or are the factory specs a MINIMUM amount of fuel required?
If I am running rich, why would that be if my fuel pressures are within spec?
Kinda lost at this point now...
