USA's "Rush" and "Satisfaction" deliver their weakest performances to date in week five.

One week after delivering its best performance on record, USA Network’s “Rush” posted its worst numbers to date.

Thursday’s “Rush” dipped to a 0.4 adults 18-49 rating with 1.55 million viewers. The adults 18-49 rating ties a pre-existing series low, but the viewership count is the least ever drawn by the series. None of the previous episodes attracted less than 1.64 million viewers.

Last week’s episode delivered a stronger 0.5 adults 18-49 rating with 1.83 million viewers.

Lead-out drama “Satisfaction,” which has endured a decline in total viewership each week since premiering, continued that undesirable trend Thursday.

This week’s episode drew just 1.14 million viewers, which marks a decline of 19% from the previous week’s audience count.

With just a 0.3 adults 18-49 rating, this week’s broadcast set a new low mark in the demo. No previous episode had gone below a 0.4.

Last week’s “Satisfaction” drew a 0.4 with 1.40 million viewers.
