Thanks, Gerry! This is a great reminder to read documents carefully. The WHO document, in the main section, recommends locating mapping sensors “…every 5-10 metres” and thi sis followed by a footnote. In this case the footnote is EXTREMELY important, as it says at the bottom of that page “ “In very large facilities, this can be up to 20 or 30 metres.” For the examples in the webinar, we were dealing with a 4000 square meter facility, which I would say qualifies as a very large facility. Now we have a documented source for the 20 meter recommendation. And you may note, they even allow up to 30 meters!
