PS 3 : Stats progression isn't static ?

[Moonlight Shadow]

Hello, Phantasy Star fans. Been a while i did'nt return here.

While i was playing -again- to Phantasy Star 3, i took some notes to know rapidly how to do to not spend much time (exemple : first go to Yaata buy 2 Htg Knives, or here there is only 4 protective equipements to buy, pr stay here and grind to buy 2 Laser Needlers, etc...)

And I realized Mieu had'nt the same stats between my two games : here is a comparison at level 18, without equipement, just in front of Cille's king.
Old game - Current game
HP : 67 - 67
TP : 42 - 51
Speed : 47 - 53
Damage : 51 - 48
Defense : 49 - 53
Intel : 31 - 37
Stamina : 33 - 33
Luck : 32 - 35
Skill : 58 - 56

So, does anyone knows how the stats progression works ? Is it random, or is it based on the way we play (I often use techs : i earn some additional tps) ? For me, i've only the impression that i proceed faster though the Rhys adventure than usually (I only bought a second Claw, then 2 Htg Claws and an Htg Vest for the actual game ; in my previous game, i bought the best equipements, ie Steel Claws, Steel Vest, Htg Ribbon, Force Boots). Or, perhaps it is because she holds the Sapphire (in her inventory, not equipped), i have no idea at all...

Stat progression is randomized in PSIII; each character has a growth value for each stat, and how much each stat increases when they level up is based around those amounts. When you're close to gaining a level, you could save, level up, reload, then level up again, and probably have different stats each time. I don't know if the random amounts are based on the internal clock or the RNG, though.

According to the Aridia editor, Mieu's growth rates are:
HP: 2.5
TP: 2
Attack: 2.5
Defense: 2.5
Speed: 2
Skill: 2
Luck: 2
