Wow that could really be a typo in that Bentley manual .
I have the equivalent VW tension gauge (looks exactly like it) and the reading is taken halfway between Cam Sprock and Inj Sprock.
I'm so overboard with my belt/timing parameters that I even count the belt cogs to verify centered. lol
The tool (new in package) was not too expensive on eBay and very gratifying to know you REALLY have it right. Maybe by genetic coincidence, my comfort level hits the range most every time without re-adjusting.
Still consider it a highly valuable tool for doing the belts and still check them all each time. Belt, bearings and seals life/wear are less stress in the back of my mind after buying the tension measuring tool some years ago.
