Retraining rule about hit points

retraining:

Sometimes the dice aren't in your favor when you gain a level and the hit points you roll are especially low. Unlike retraining other character abilities, retraining hit points doesn't involve replacing an existing ability with a new one, it just increases your maximum hit points.

Retraining hit points takes 3 days and requires you to spend time at a martial academy, monk monastery, or with some kind of master of combat who is at least one level higher than you. At the end of the training period, increase your hit points by 1. You can retrain hit points only if your maximum hit point total is less than the maximum possible hit point total for your character.

Example: If you are a fighter 5 with Constitution 14 and you haven't allocated any of your favored class bonus to hit points, your maximum possible hit point total is 60: (d10 HD + 2 from Constitution) × 5 levels. If your maximum hit point total is already 60, you can't retrain hit points because you are already at the limit. If you took the Toughness feat, you would gain 5 hit points and your maximum possible hit point total would also increase by 5, which means your ability to retrain hit points would be the same as without the feat.

Tings in 《PATHFINDER SOCIETY ROLEPLAYING GUILD GUIDE》

Hit Points:

Consult the table below to find the appropriate valuefor that die. A 1st-level Roleplaying Guild charactergains the number of hit points listed in the Hit Pointsat 1st Level column for her class—this is the maximumvalue on the class’s hit die. For all subsequent levels(including when gaining 1st level in another class), the character gains the number of hit points listed for the new class in the Hit Points at Level 2+ column of the table below.

Retraining:

After 1st level, if you own a copy ofPathfinder RPG Ultimate Campaign, you can use theretraining rules beginning on page 188 to alteryour character. All changes must be tracked on your Chronicle sheets or Inventory Tracking Sheets, made inthe presence of a Roleplaying Guild GM, and initialedby the observing GM. The GM can audit your characterbefore allowing changes, so bring your character sheetand all Chronicle sheets to the GM. Retraining may belimited by time constraints. When retraining, playersmust expend wealth as outlined in the Retrainingsection of Ultimate Campaign, as well as 1 Prestige Pointper day of retraining since time between adventures isundefined.

My opinion is，since“You can retrain hit points only if your maximum hit point total is less than the maximum possible hit point total for your character”，and in PFS games your hp is a certain number according to the table,there are no other possibilities,so you can't retrain your hit point,is that right?

[GM Eazy-Earl]

You can retrain your hit points in organized play, though whether the benefit is worth the cost or not has been debated.

[Starglim]

Your class hit dice are still expressed by the Pathfinder rules as dice, even if you don't actually roll them. The maximum possible hit point total is the maximum result on each hit die, above first level (which is already maximised), plus modifiers. You can certainly have more than the average + 1. Depending on your class it will take quite a bit of PP spending to hit the limit.

[Shinae]

So it's 3 PP and gold cost of 10x lvl x 3 days it takes to retrain (basicly 30g x level)? Or only 3PP per hit point?

I have several characters I don't really plan to ress if they die, so I might as well retrain extra hp for them.

[DesolateHarmony]

You use the rules in Ultimate Campaign, and in PFS, the ability to get and use a trainer is covered by the Prestige Point cost, which is one PP per day. Both gold and prestige are spent.
