What data are you refering to? Why does anyone even bother? There is no data presented, no need to get too scientific about everything. Postings from members are simply sharing personal practical experiences on the board about their driving/ownership habits. It is upto the reader to ingest the information and make a decision himself.
FWIW, the manual does not produce any irrefutable data or their consequences too.
Driving a car is to get maximum enjoyment during its ownership timespan, drive it anyway you choose too and enjoy it.
