[ECI-EN] Uncoated profile total ink

Dear ECI members, I was looking at your icc-profile for uncoated paper (PSO Uncoated ISO 12647) and noticed it seems to have a maximum total ink coverage of about 290%. Isn't that way too much for uncoated paper? Every printer I've spoken to agrees 260% should be the limit, or the print will be too dark and dry slowly. Most people using your profiles convert the limit to 260% in their RIP. Would be interesting to hear your view on this. Thank you.
