I allow the TM to produce backups at its own pace, not forced to a rigid schedule by some third party app. The tabs on the right of the TM screen show the correct times, properly interspersed as one would expect. If one of my devices is slower than the other (another computer backing up to it) the tabs on the right of the TM screen are magenta for the faster responding device and the other stay white until the second device responds.
