A tight spread with high depth is a market you can move size in. A wide spread with low depth moves against you the moment you buy.

Each day is indexed against the week around it, item by item, so neither an expensive item nor a market that drifted over the quarter can tilt the table, and the seven are then centred so an average week reads 1.000. Under 1.000 is a cheap day to buy; over 1.000 is a good day to sell. The Days column counts the days behind each figure, not the readings, so read it once there are several weeks there.
