I'm not sure if there is an issue with the SA ranges or not, but I've double checked my end, and it seems to be right, so not sure if I'm just missing something or not.
At the moment to me I'm seeing that the range for SA's 9th set of 500 caches goes up until the 9th May, but GCA says the 19th. I've kept an eye on it for the last week or so just to see if it was some archived caches that hadn't filtered through yet, but the dates haven't changed, so I am wondering if I've got something wrong, or if the feed has played up somewhere along the lines. I've imported the PQ's from the 9 and 10 PQ's just to see if GCA was missing some caches, but it doesn't appear so.
The only thing that makes me query it, is that GSAK is showing as completely up to date using the ranges that I've got set (up until the 9th May for the 9th PQ, and then from the 10th May for the 10th PQ), so I'm not sure where things are different.
Probably making no sense, but just thought I'd raise it, and try an explain it in some form.
