SA-2 Volhov with V-755 performance and atributes BUG

[GumidekCZ]

I couple of mission, I noticed that SA-2 range limits was reduced significantly - can be compared with an older SA-2 Desna system. So I went into DCS scritps and compared values there with the real world values for Volhov system with V-755 (20D) missile.

SNR_75V.lua (Fan Song TR radar):
beamWidth = 1.5707963267949,
distanceMax = 100000,
distanceMin = 1500,
max_trg_alt = 20000,
min_trg_alt = 25,

S_75M_Volhov.lua (Launcher)
ThreatRange = 43000,
ThreatRangeMin = 7000,
distanceMax = 43000,
distanceMin = 7000,
maxTargetDetectionRange = 65000

SA2V755.lua (V-755 20D missile)
D_max = 40000, - Max Range at min Alt of 100m
D_min = 7000,    - Min Range
H_max = 25000, - Max Altitude
H_min = 100  ,    - Min Altitude
KillDistance = 20,
Nr_max = 17,
PN_coeffs = { 2, 1000, 1, 40000, 0.5 },
Range_max = 30000, - Max Range at max Alt of 25km
ccm_k0 = 3,

90° Degree Radar Beam? Wide Beam setting of FanSong radar was 20°

Missile fuze was set to standard 100m, or can be set to 300m for large target like B-52.

Max speed and overload capability (depending on target altitude):
at 300m altitude, 785m/s (Mach2.6), 5.5~6g
at 10km altitude, 910m/s (Mach3), 5.5~6.5g
at 25km altitude, 1125m/s (Mach3.7), 2.7~3g
at 30km altitude, 1230m/s (Mach4), 2.1~2.4g

Missile guidance was able to guide via HALF-LEAD (PN=0.5) or LOS (on beam PN=0), never Pure Lead PN=1

Now to Missile limits. Lets say, that roof latitude for DCS aircrafts is 15km (50 000ft), so the aim of accuracy is to suit missile depicted Range limits to this altitude - orange lines. Green lines represent actual maximum limits of the missile with linear approximation between these values.

New suggested missile values according to S-75M or V-755 20D missile charts:

D_max = 28000,        - Max Range at min Alt of 300 m
D_min = 7000,          - Min Range Correct
H_max = 30000,        - Max Altitude
H_min = 300,          - V-755 20D minimum altitude
Range_max = 48000, - Max Range at max Alt of 30 km
