This is how statgain works, I will use str as example however all 3 stats are checked after @SkillGain (even if there is no skillgain):

local.stat=<str>
local.cap=<serv.skill.<action>.bonus_str> //gets max bonus_stat from the succeeding skill.

local.difficulty = <muldiv <local.stat>,1000,<local.cap>>

local.chance =<eval 100000 / <f_Value_GetLinear <local.difficulty>,<local.cap>,<serv.skill.<action>.values>> > // f_Value_GetLinear function is inside sphere_combat, it get's the actual 'point' in which you really are in the ADV_RATE or VALUES, so if you have ADV_RATE=1.0,50.0,90,0 and your skill is at 99.0 you'll get as return something close to 88.7~.
if (<local.chance < 1 )
return 0
endif

local.roll=<r1000>

local.decrease=<stat_decrease> //just internal function checking if any stat must decrease, ex: passed the cap of stat, of total stats, etc. and automatically decrease that stat, its also returns 1 if the stat gain is allowed to happen regardless of the stat's decrease.
if (<local.roll> <= <local.chance> && <local.decrease>)
gained your stat point!
endif


EDIT: Forgot the most important for you: change your BONUS_STATS to 100, this should make you have more gains.
