Always start with a 4 step spread. If the standard edge lift is good every where but the 6 o’clock position, then you order a 4 steep at 270 degrees.
Order like this: standard at 90 degrees, 4 steep at 270 degrees, with 1 D. prism at 270 degrees.
Example 2: Too tight at 90 degrees and too loose at 270 degrees: flatten the 90 and steepen the 270.
Order like this: 2 steps flat at 90 degrees, 2 steps steep at 270 degrees, with 1 D. prism at 270 degrees.
** You may have to end up with more or less than a 4 step spread, but this is the starting point.
Example 3: Seal off at 3 o’clock but standard edge lift looks good everywhere else.
Order: Standard at 90 degrees, 4 steps flat at 270 degrees, with 1 D. prism at 180 degrees. This will position the lens with the flat edge portion at 0 degrees or at 3 o’clock.
