Good news. My dad and I decided it was time to crack open another capped bottle to see if carbonation had increased. We moved the bottles from the closet into the refrigerator for about a day before we opened them. Keep in mind at this point, the bottles have now been conditioned for about 3 weeks. Success!
We were surprised at the increase in carb from week 2 to week 3. We attributed the fact partially to giving each of the bottles a swirl to rouse up the yeast back into suspension back in week 2. We're not 100% positive that's what did the trick, but the capped bottles are now producing the same amount of head as the Grolsch swing caps.
