It should be
Sigma 8mm F3.5 for Nikon (4 around), Quick release handle at left.
+7.5-----1.15
+5-------1.5
0---------2.2
-2.5------2.5
-7.5------3.2

There is no problem in reading values like 3.6 or 3.65 for a scale that is max at 3.5. There are 2 auxiliary lines which are 0.15cm away from the center line. Using these lines, you can ready up to 3.65.

PS the lens ring plate/ rail is right for your model. You don't get any benefit to use -7.5 deg tilt on a tripod. The tripod and Rotator D4 block more than 10 deg. Tilting down more than 2.5 won't do you any good.
Sorry please take a look on your "users manual" for R1 http://www.nodalninja.com/R1_quick_r...front_back.pdf

Your advice for sigma 8 mm / 3,5 for Nikon is there:

+12,5 ---- 0,70
+ 7,5 ---- 1,25
+ 5 ----- 1,6
0 ----- 2,25
- 2,5 ----- 2,55
- 7,5 ----- 3,75

Please let me try tomorrow again with the new numbers. Thank your for your answer.
