Yogi: Sometimes the awareness of awareness is clear and sometimes not; I cannot detect greed or aversion when it’s unclear – perhaps delusion is present.

Sayadaw: As much as the mind understands it, that’s how clearly you can experience it; and when the understanding is not strong for whatever reason, then, it won’t be clear.

At the gross level, there aren’t the lobha-dosa, but at the subtler level there may be some lobha-dosa besides the delusion.

Regardless of whether it’s clear or not, the practice continues; only just recognizing that now it is and now it is not, and carry on. 

Sitting is a quieter activity – it gives us more continuity and builds the power of the awareness and with that comes some wisdom. So, the object has a chance to become clearer. 

In other activities there are more movement and agitation, and if the power of wisdom doesn’t grow to match the activity, then it cannot be as clear.
