Measuring blocks 90 & 93. Can anyone explain what fields 3 & 4 in each...

are actually measuring?

90 Camshaft adjustment (values are for idle & road test: accel in 2nd gear)

90,1,Engine speed,RPM
90,2,Adj ON/OFF,idle=OFF/rt=ON
90,3,Adj resp Bank1,-3-6/16-25degKW
90,4,Adj resp Bank2,-3-6/16-25degKW

What does the -3-6 represent? Is it minus 3 minus 6 or minus 3 to 6?
What does 16-25 represent? I assume this value reads as 16 to 25 degrees?

93 Phase Positions of Cam Pos Sensors

93,1,Engine Speed,Rpm
93,2,Last,%
93,3,Phase Bank 1,-15 to 10 deg
93,4,Phase Bank 2,-15 to 10 deg

What does -15 to 10 degrees represent? Is that the tolerance? I can't find anything in the Bentley addressing any questions I asked in this post.

Thanks to our old buddy Dave (Skiwi) and his label files thread from the early AW days. I was able to copy/paste the measuring block label info :-)
