Okay, that sounds more like it!
I interpreted "við" as "með".
I then found out that there were far more references to "vega at e-m"
than to "vega með e-m". (or should it be e-n?)

Please regard my doubts as cartesian in nature.
(doubt as "method")

I guess that is a good negation of the equality of ON with MI, then.

Ver heill!
