F800gt ABS bleed test results

[John]

Hi all
I have completed a flush of the brake fluid on the front brakes of my f800gt and then performed a brake bleed test with my gs911.
During the test a blue graph displays a percentage starting at 100% then decreasing each time I apply the brake lever as per the instructions.
I would like to know the correct results for this test and what would the indication that there is air in the system.
Thanks
Cheers John
