Yes I agree, that's why in post #8 I specified "EV at ISO 100". In fact, the use of LV instead of "EV at ISO 100" as a measure of illuminance is not really standard as well:
where is says:
Recently, articles on many web sites have used light value (LV) to denote EV at ISO 100. However, this term does not derive from a standards body, and has had several conflicting definitions.
I agree that LV is faster - and more sensible - than saying "Ev at ISO 100" but it's not widespread.
