The following tests suggest that all Hard and Medium Air Raids are treated as High Altitude Raids (LBAS Air Power is multiplied by 0.5, 0.8, 1.1, or 1.2 for 0, 1, 2, or 3+ High Altitude Interceptors, respectively), while Easy and Casual Air Raids are treated as normal Air Raids (no scaling).
Min. registered Air Power for the state ~ Max. registered Enemy Air Power → after scaling Δ difference with the scaled boundary
