Standoff jamming does not modify missile Ph

I was thinking whether to post this as a question for the General or open an Issue.
Common sense says that escort and standoff jamming both should influence radar guided missile hit probability, I finally decided "Issue" after I found this post of Tony http://harpgamer.com...e-notes/?p=6008

Test scenario is in HDS1.
Two flight of bombers are loitering just NE of Kinloss.

• ZXA 4 x Tu-16 Bmbr + 1 x Tu-16 J EW
• ZYA 4 x Tu-16 Bmbr

The two groups are on top of each other, ZXA at High, ZYA at Medium
4 F-14s are ready to assist with the test just 3nm S of them.
(savegame: EW)

Firing 4 x AIM120 at ZXA000 (the escorted Badgers) yields PH 45

101455 combat3.c:1477 - AirToAirResolution Ph: 45, Roll: 38
101455 combat3.c:1477 - AirToAirResolution Ph: 45, Roll: 98
101455 combat3.c:1477 - AirToAirResolution Ph: 45, Roll: 89
101455 combat3.c:1477 - AirToAirResolution Ph: 45, Roll: 29
101455 effect4.c:5176 - CheckAirMissileHits 4 x AIM-120 AMRAAM against RED 4 x Tu-16 Badger G, 2 hits

As far as I can tell that is 40 DPh for AMRAAM + 30 - 20 for escort Tu-16 ECM - 5 for Tu-16 Bmbr DATA

Firing 4 x AIM120 at ZYA000 (the "standoffed" Badgers) yields PH 65

101462 combat3.c:1477 - AirToAirResolution Ph: 65, Roll: 27
101462 combat3.c:1477 - AirToAirResolution Ph: 65, Roll: 3

101462 effect4.c:5176 - CheckAirMissileHits 4 x AIM-120 AMRAAM against RED 4 x Tu-16 Badger G, 4 hits

E.g. no standoff jamming bonus of -20 PH for the Badgers

Just to crosscheck kill of the EW bird, with AIM9 of course, confirms nicely that IR AAM is unaffected by EW and attack again remainder of ZXA, now without EW escort gives same PH 65

101529 combat3.c:1477 - AirToAirResolution Ph: 65, Roll: 0
101529 combat3.c:1477 - AirToAirResolution Ph: 65, Roll: 35

101529 effect4.c:5176 - CheckAirMissileHits 4 x AIM-120 AMRAAM against RED 4 x Tu-16 Badger G, 4 hits

I expected and posts suggest too that ZYA should have also received the PH bonus against AAMs.
