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
1HVAC 105 252 60%
DIYCool 63 140 100%

“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.
