I never compared until now the balance from my bookie account with those in this thread (and of course over there are not in "Units").
Now when I compared these values, I realized I had several errors when showing this balance here - all where in cases when one leg of the parlay was "half lost".
Here are all the corrections for "Overall":
On Oct 3:
Old, with error: L 1 U ; New, correct: L 0.12 U (0.38-0.5)
On Oct 4:
Old, with error: L 1.15 U ; New, correct: L 0.161 U (0.414-0.575)
On Oct 14:
Old, with error: L 2.15 U ; New, correct: L 0.387 U (-1.075+0.688)
Difference New / Old = +3.632 (-0.668 / -4.3)
Corrected Overall: W 7 - L 9 => W 7.362 U
