The frames count the same detector job on different bases -- a by-type unit and installation split plus a by-count total table in Frame A against a per-unit installed total in Frame B. Frame A prints its unit and installation lines apart inside its own frame alone; Frame B prints its installed totals inside its own frame alone. Those differences are named as frame differences on every page, never averaged.
The neighbours, differentiated
The standing new homeowner hidden costs guide carries a detector line as one unpriced line with no priced rows, and the hidden-costs guide prices the whole first-year list; this cluster prices detector installations alone.
The local read
The local read: the frames above are national published frames, and a written quote for one address, one detector type, and one count is the only local figure; the frames stand as published, apart, and never blended into a local band.
