How much of each range overlaps

Each brand's range, and how much of it is shared with the other
Brand	Units in the certified data	Certified combinations	Share of its range that is shared
Evcon	11	571	100%
Guardian	35	618	31.4%

“Share of its range” is shared model numbers divided by that brand's own units. The two shares differ because the two ranges are different sizes. One row per unit (a certified model number), not per brand entry.
