I have met and chatted, both in person and on line, with a ton of editors from various MSCs, as well and attended panels of editors at conferences. The one thing on which they agree is that they value reliability above all else. Many will cheerfully correct syntax, grammar and usage for a shopper who is super reliable and provides useful comments meeting the guidelines. They value clarity, reliability and objectivity above grammar and syntax.
In addition, with many shoppers entering even complex reports using voice to text applications, editors cherish some really striking "wordo-s." (As in, "The valet's shirt was holy." This resulted in a demerit for attire and grooming, of course.)
Finally, I know a number of shoppers and a couple of MSC managers who, although fluent in English as their second (or third or fourth language) have been led astray by relying on a Thesaurus for guidance, with hilarious and or baffling results.. (As in, "The new system may be in place everywhere except Philadelphia, which has not yet been screwed up."" Except that the word used was not "screwed".)
So, let us all be aware of he possibility that some folks whose written prose may be an issue may also be making positive contributions.
