If it is a day I have lots to do I am more likely just to do them in a row. SA tools make it easy to keep up with which ones I have done that day.
As for time of day I usually go for most convenient but since my life has become more routine that becomes more likely to be the same time. If I am in a dry spell( no wins in a week) I will make myself do them at a different time.
The main key is to be sure you enter them.
