Yes, delays are to be expected. However, if you experience the counter going down even though you didn’t delete submissions, it is a different issue, which probably has to do with a bug in how the script downloads and stores the results in cache. To force a cache refresh, make sure you close all tabs from
farm.pcibex.net (eg. quit your browser), visit your project again and try downloading your results. If the number seems off, try that process again once or twice. If the problem persists, it means there either is a delay in how the database handles incoming submissions, or an error caused some data loss
I am happy to check the server for you by the end of the week, but could you please remind me about it by posting a message here then?
