Hi Ray,

Yes, I understood that. That's why I'm suggesting that this can either be a
supporting point for my proposal or alternatively, we need to establish an
objective criteria.

My position, obviously is that it will be better to just remove this
section, as I don't think the situation will change drastically in terms of
consumption.

Regards,
Jordi
