Small Lab in Office w/ Multiple Controls

Hi, My project is a winery with a 300 square foot lab. There are three workstations, but only two employees work there most of the time. None have task lighting per se, but the overhead lighting has four different settings: on/off, center pendants, perimeter lighting and counter. The perimeter control provides task-like lighting because it lights directly above two of the workstations and can be isolated from the overhead lighting control. When inputting the number of workspaces w/ lighting controls, what number would you recommend putting in? I could see either inputting 2 if the perimeter lighting counts as task lighting, or 3 since every station has access to 4 lighting controls.
