If Split drivers aren't taking buses out and back then they are effectively pointless as you don't save any standard duties.
The spread time is sixteen hours. Not many splits maximise the spread time, and most seem to fall at around just over twelve hours in total. The overwhelming majority of split duties will involve taking a bus from the depot in the morning and returning it after its miscellaneous runs, and then doing the same again in the afternoon; some morning splits will be relieved at an interchange, and the driver might then have a period on standby before being free to make their way back to the depot.
At Riverside and Washington, for example, some split duties will finish their morning segment at Gateshead Metro or the Galleries as some miscellaneous boards run onto regular services, although this applies more-so to Riverside.
Some splits will start earlier then the other splits but also conclude earlier; I remember at Chester, there was a split shift that was one of the first buses out of the depot (the staff bus), and then didn't conclude until nearly 0930, before doing a single scholars run in the afternoon and wrapping up just after 1700. From my observations of how the splits drivers worked at Chester, most of whom had worked there for a considerable time, each line on the splits rota would entail the same shift Monday through Friday so that a driver would have the same shift all week, then might not do that shift for another four weeks.
