To avoid perilous double-weighting is an important concept of tài-jí-quán (太極拳). Dejan Djurdjevic, too, wrote an article or rather an essay on this topic. Especially his third footnote is very interesting! According to it, neither my nor Dejan Djurdjevic’ explanation of the topic would be accurate. Double-weighting would mean to meet force with force and thus the weaker party would lose and hence has only an advantage from learning a martial art, which teaches to avoid this. So the strict rule to avoid double-weighting would on the one hand equal the principles of aikidō (合気道) and on the other hand be an application of the principles of yīn (陰) and yáng (陽). Then is no wonder that ‘hard styles’ don’t necessarily know double-weighting and its perils. Although meeting force with force in the opposite direction never is a great idea and ‘hard styles’, too, should at least teach this much. Distributing weight equally on both feet nevertheless is another way to neglect the principles of yīn (陰) and yáng (陽), so still a bad idea if considering the concepts of tài-jí-quán (太極拳). Dejan Djurdjevic’ concept of ‘preservation of momentum’ certainly isn’t wrong, but the explanation in his essay seems to me to be rather an explanation of how to make your opponent’s leg-sweeps work. {Attempted leg-sweeps are in combat sports often only an excuse for kicking the opponent’s shin and in sumō (相撲) caused the strange rule that you may kick your opponent only below the belt. Several moves despite being standard techniques in combat sports as well as in martial arts have the reputation to fail most times.}
