It depends entirely on the size of the property, we only did one property today and that was only a dining room, stairs, landing and bedroom with en suite they were not very dirty but large, and that was two of us working. Other days I may do two jobs in a day but never more than two. Anyone who is knocking out three jobs a day is cutting corners.
As for drying times i explain all of that at the quotation stage so people know what to expect before committing. Dry times should be hours rather than days so the majority of people are not worried.
