Store TP info can be found in the SAM forums.
Anyway, the point of these is that with a 450 Delay GKT, such as the level 50 Koryukagemitsu, you need 46 StP to reach a 6 hit build. At 50, you get Store TP trait III, which gives you 20 flat-out. This leaves you needing 26 more. If you equip the Shinamusha Hara-Ate + Shinamusha Haidate then you have added 15, for a total of 35 (leaving 11 to go). Now, equip Rajas Ring and you are only 6 away.
For the final 6, you have two options.
Option 1) Carbonara
Food Effects: (30 Minutes, All Races)
HP +14% (Cap: 175 @ 1249 Base HP)
MP +10
Strength +4
Vitality +2
Intelligence -3
Attack +18% (Cap: 65 @ 361 Base Attack)
Store TP +6
Option 2) Arrabbiata + Ecphoria Ring
Food Effects: (30 minutes, All Races)
HP +12% (Cap: 150@1250 Base HP)
Strength +5
Vitality +2
Intelligence -7
Attack +22.5% (Cap: 120@533 Base Attack)
Store TP +5
Note that you get one more STR and more ATK with Arrabbiata, but that due to it only having 5 versus 6 StP, you need to add 1 more from your ring slot. Also, since it is made with Dragon Meat, price may be prohibitive.
Hopefully this information clears up the confusion that was posted below.
As a final note, people using Soboro Sukehiro should not be focusing their gear on StP.
