Should I wait a level to Loremaster?

[Jinotad]

I’ve been looking at my wizard, Clayr. Let me give you a brief introduction. I am playing PFS.

Clayr is a gnome wizard, who is currently level 7, ready to level up to 8. She is obsessed with knowleges, currently sitting at a minimum +13 to any knowledge, up to a +25 on knowledge history. I have been prepping Clayr for becoming a Loremaster, which she can start at level 8.

If I choose to stay wizard for 1 more level, I will gain +1 initiative, +1 History, +1 Local, and Scrying Adept (Su): (At 8th level, you are always aware when you are being observed via magic, as if you had a permanent detect scrying. In addition to bonuses to scrying.)

What are peoples opinions, on whether or not I should delay getting the prestige until level 9? That would still give me 3 levels of Lore Master by level 11, 5 at level 13. If I started Loremaster at level 8, then I would be Level 6 Lore by level 13, giving me the Greater Lore (Ex): (Whenever a loremaster examines a magic item to determine its properties, he gains a +10 circumstance bonus on his Spellcraft skill check.)
I don’t know how much importance that would be for a retirement arc.

Loremaster Class

The restricted career space of PFS (normally stopping at level 12(*)) makes this tough. However, in this particular case, the additional ability that you would get for starting Loremaster at 8 instead of 9 would be a bonus language (which you can get in other ways), which seems less important than what you get from Wizard level 8 (which you can't get in other ways).

(*)Do you have some kind of boon that lets you keep going through level 13?

I do not, I thought the retirement arcs took you from 11 to 13 for some reason.

And for the bonus language on this character is even more week than normal, due to the Gnome trait that allows me to learn two languages per rank in linguistics.

I do know that there are a few scenarios that allow you to play with higher level characters, so I am keeping that in mind.

Clayr is a Scroll scholar, which is where the +1 history and local come from.
