I was in Napa recently and they had some fliers on the shelf addressing this. I don't recall the verbiage exactly, but it was pretty clear they recommended the Silver for the more modest OCI's, 3-4k I think.
Sure they should (and I'd expect will) handle any manufacturers interval but longer OCI's are not what they are really intended for.
I would run a Gold for 10k without hesitation but wouldn't personally do it with a Silver, and I am a big fan of the Silvers.
