+1!
It's 225 nominal, and I just tried it on RSG #1. From the tee, it got stuck in the rough before the fairway, thus went only 200 yds. Second shot with minimal tailwind went 241 to the side of the green with barely 190 yds carry - see replay.
Edit: This would be valid for the G20 irons:
Alas, your numbers are misleading. The 3WD is 240/225 yds but the 3I is 215 yds (4I @200). Thus the gap is not that big.
Edit: With the Rapture irons, the gap should be as you said...
