Proportional Armor Table
When layering armor or wearing armor behind an obstacle or cover, subtract the smaller SP from the large one. Find the difference on the table and read across to the other column. This is the bonus number you add to the LARGER SP to determine OVERALL protection from the armor/armor or armor/cover combination. If you have three or more layers of protection, calculate in pairs from the inside out. [ ex.: For armors A,B,C, you compare A and B, determine B's bonus number and then compare the new strength of B to armor C. ]
| Difference | Bonus SP |
| 0-4 | +5 |
| 5-8 | +4 |
| 9-14 | +3 |
| 15-20 | +2 |
| 21-26 | +1 |
| 27+ | 0 |
