[Star Wars EU] How much service did the Victory class and Imperator class star destroyers see during the clone wars conflict?

The victory class star destroyer was introduced around 20 BBY and first saw combat under Captain Doddannas Victroy fleet (sent against the Seperatist Bulwark fleets).
Meanwhile the Imperator class destroyer was introduced during 19BBY. 

Both ships apparently were actually used by the Republic along with the Venator, acclamator, and Tector class destroyers (the Tector saw barely any use after its field test proved disastrous).

Though how much service/use exactly did the Victory and Imperator see in the clone wars conflict?

While it is noted that the so-called "Victory Fleet" was put into combat against the Seperatist units threatening Coruscant, it is also noted that "majority of the initial commission group" was not deployed until the Clone Wars ended. It seems very likely that the existing Victories were held in reserve to continue defending Coruscant Sector until the war's end; in this role, we know they participated in the final defense of Coruscant.

We actually know less about the Imperator/Imperial-class' record of general service. Some were in service with "several Republic task forces", and arguably the fact that both Venator- and Victory-class' production was still being slowed to make way for Imperators suggests that the type had enough service to prove itself in combat as a more valuable vessel. Actual details, however, are scarce.
