I've done that at other places of employment. 6.67 hours to be exact . But we used it to account for email time, walk-ins, bathroom, water cooler, coffee, etc. For meetings etc., we create a task to log time and account for resource planning. For Training, if it's related to the project we definitely create its own task to account for the time etc. If it's unrelated to the project we just have the person block that time off in their calendar so it moves their tasks around that time slot.
