Materia meld caps for Disciples of Land #2

[Squand]

Forager's offhand meld question.
I just got lucis tools and have now full BiS set. All gear and accessories are fully melded, offhand - no.
My current stats are 478 gath, 461 per, 636 gp.
Now i am thinking about meld strategy for offhands.
I see that i want to have 4 more gp or 2 at least to be able to reach 650 gp using food with nonprimary gp bonus - Haddock Dip (gp+10/12), Crowned Pie (gp+10). So, i plan to meld gp materia 4 first. And i don't understand what to meld next - perception? Or gathering > 478 may be useful too? As i understood hardest to get items are non hq and i have enough stats to get them.

I had to be at 492 gathering to hit Virgin Basilisk and Rossmarry in one go. Which meant Maxing Gathering in my off hand. (My guess is the threshold is 490)
