RG20th serial numbers?

[Inzane]

I just had a question regarding the serial number on the RG550 20th anni re-issues. Below is a quote from another site http://www.ibanezcollectors.com/disc...5751/8404.html

starting with Japanese built guitars:
1997 to Now
F=Fujigen factory,
2nd & 3rd digit=year made(eg 04=2004)
next 5 digits =month & build number
Jan=5000
Feb=10000
Mar=15000
Apr=20000
May=25000
June=30000
July=35000
Aug=40000
Sept=45000
Oct=50000
Nov=55000
Dec=60000

So an example here is for a recent model with a Serial number F0330210 = Fujigen 2003 June 210th guitar built.

Looking at my headstock it appears the number is F0700030.
So mine would be Fujigen, 2007, 30th built? But what month? Is '00000' representing January in this case? (as opposed to 05000 or 5000)

i guess its Fujigen 2007 30th (in overall production not just for rg20th)
Theres no month info on serial numbers.
