They seem to be treating yoga and meditation separately. Perhaps, they need to understand that yoga has 8 limbs, one of which is asana (generally what most people consider yoga). Yoga has 4 limbs/levels of meditation. Suposedly, one can't have an ego to reach samadhi (the highest level of meditation). The yama, niyamas, asana (what most people yoga) and pranayama (breathing exercises) limbs of yoga are steps or precursors to the meditation. Seems like they don't know this and are testing beginners; I am not sure how meaningful that is. If they had a way to measure how compent each person was at each limb and then gave results based upon their skill at each limb, that would be interesting. Not sure how one would measure whether a person is competent at the 4 meditation levels.
