[ECI-EN] "ISO coated v2 (ECI)" and "ISO coated v2 300% (ECI)"

I'm a little confused about the use of the new profiles "ISO coated v2 (ECI)" and "ISO coated v2 300% (ECI)". ECI states on there website: "For two standard offset printing conditions new profiles are available. ECI, bvdm and FOGRA jointly recommend the use of "ISO Coated v2 (ECI)" and "ISO Coated v2 300% (ECI)". The latter is a version with lower maximum ink coverage (300%) suitable for e.g. heat set web offset." As I interpret your text, the profile "ISO Coated v2 (ECI)" is for Sheet-fed offset and the profile "ISO Coated v2 300% (ECI)" is suitable for heat-set web offset. Now. on Ugra's website I have found this text: "The new profile ISOcoated_V2_300.icc is used for the separation of data. If there should occur problems with insufficient blacks, the profile ISOcoated_V2.icc with a total area coverage of 330% should be used. swiss4color recommends however, to use the profile with the total area coverage of 300%.". Should I use "ISO Coated v2 (ECI)" for Sheet-fed offset and "ISO Coated v2 300% (ECI)" for heat-set web offset? Or is it like Ugra wrote on there website, always "ISO Coated v2 300% (ECI)" for Sheet-fed offset, and only if I should experience problems with insufficient black, then to use the profile "ISOcoated V2 (ECI)".
