Actually, I estimated his internal energy from the descriptions (at that particular age) of Mighty Dragon Without Regrets. QF was able to propagate his force from 150 feet. GJ propagated his force merely from a distance. If you take into account that this was in a courtyard that cannot be more than 50 feet wide in any direction, GJ's feat falls short of QF's. Hence I would say that he is not as powerful as QF at this age. I also said that GJ could be a match in the future because of 9 Yin so that his internal energy will in fact increase very rapidly.
