More programs have a YOG cut off than a 220 cut off.
I'm not saying a low score, but anything above 220. If you're a fresh grad (2013) with a flawless profile, you're almost guaranteed an invite to most IMG-friendly programs.
Many, many programs have a 3 year cut off.
A 260 is way above average. Of course someone with a score like this will get insane amounts of invitations even if he/she graduated 4 years ago. But most programs prefer 220s/2013 over 230s/2009.
That said, provided you're within the 5 YOG cutoff, if you feel you can bump your score up by 20 points, then by all means, take an extra year. Especially if you're bumping from 210 to 230; 230 to 250.
