265 days / 2 = 132.5 hours at 3 JP/hr = ~400 job points

Assuming that "hundreds" means >200, tossing in a few double campaigns, and assuming the other things you're saying are true, then you've spent about half your FFXI playtime since the patch soloing job points. That sounds miserable. Just set up a good CP party a few times during the double CP campaign and get >10 JP/hr.
