The main page with the full country listings doesn't deduct DR for attacks. The actual country page for it does (the thing that says "more accurate"), but doesn't list the amount of DR deducted for each attack (lists only a dash sign).

Basically, you have major inconsistencies in how the DR values are calculated and displayed on different pages.

Edit: Not only that, failed specials on a country doesn't add to its DR, but you have DR displayed for that attack. Likewise, missiles don't add or remove DR (they don't affect DR at all), but they also have DR values displayed.
