Twice the EDR

in Strictly Steam
Admittedly, I don't do much steam but this really puzzles me. I looked at a steam boiler today that had almost twice the EDR (Peerless 61-08, 704 EDR) than the connected EDR (360). I was shocked when I walked into the boiler room. The home is only 1600 square feet.
How often do you guys see this? I see hot water boilers oversized all the time but rarely by this much.

    Stephen I see this all the time on average about 25% of the time. Most of them are actually on fairly the new side.

    It's a constant problem.
    And then the jenius (intentional spelling error) that installed it tells the owner the problem is steam and to rip it out and install forced hot dust.
