When stuff like this happens repeatedly where the editor misinterprets guidelines for the same shop or different ones and the shopper is correct, Ipsos should test the editor with similar reports to see how the editor grades it. It seems like rejected reports have a slim chance of getting overturned based on other posts here.
If they tested editors then IPSOS would know if an editor is misinterpreting a shop if they gave them a perfect report followed to the T. It would need to be a situation where the reports are sent in through the portal so it appears to come from an IC and not an internal test so the editor is treating them how they normally do. Better yet, they should test the editors when they change the guidelines.
I don't get the impression the editors are spot checked for their work. Are they?
