Here is somethings you might find interesting:
Here is the script for "Delta" (NOT EVEN AN OPTION IN THE GAME THOUGH!) comparing against PostHumanWarrior.

ai_RODMoveInc = 0.25
ai_RODStanceInc = 0.25

-- AI fire reaction time
ai_RODReactionTime = 0.05
ai_RODReactionDistInc = 0.05
ai_RODReactionLeanInc = 0.05
ai_RODReactionDirInc = 0.25
-- Cover fire time modifier (cover fire time specified in weapon)

-- ROD ranges - percents of attackRange AI property
ai_RODKillRangeMod = 0.4
ai_RODCombatRangeMod = 1.0
-- Ambient fire, enemies not in the quota cannot hit the player.
ai_AmbientFireUpdateInterval = 0.5
ai_AmbientFireQuota = 10
-- Low health effect duration and health threshold
ai_RODLowHealthMercyTime = 1
g_playerLowHealthThreshold = 100
pl_health.critical_health_thresholdSP = 15

v_driverControlledMountedGuns = 0
-- Health regeneration
pl_health.normal_regeneration_rateSP = 250

It would suggest that PHW is actually even harder than delta! Now lets have some fun and make a REAL post human warrior difficulty!
