Slide Rule Targeting for SHIII/SHIV

Wow I'm sucking at this.

Ok with the circular slide rule I set the first cursor on 6100 on D scale, then set the second movable cursor on 7300 also on D scale.

Following the cursor down from 6100 it intersects the S scale at 37.6 or we can just say 38. Following the other cursor down from 7300 it intersects the S scale at 47 degrees.

What am I doing wrong?

EDIT: Are you saying you should first have a guestimate of the target's AOB when trying to squeeze in the difference between the two bearing points? The scale is long and just taking a stab at finding X number of degrees between bearing points could take a long time. So by having a guess of the AOB that can give you a ballpark figure for narrowing down the S scale to get your required number of degrees?
