What the register adds up to: how long a name lasts, which families change theirs most often,
and how long an acquired company keeps its own name. Every figure is recomputed in the browser
from the same file the register reads.
Same numbers, no colour needed.
How long a name lasts
Time to SAP-ification
Which families change names
Renames only. An acquired product taking the SAP prefix is counted in the section above
instead, and a generation change is not counted anywhere.
Renames that came in waves
Some names did not change on their own. Where two or more products moved at the same
boundary for one announced reason, the register tags them as a wave.
