That’s why I said some - more of an issue for some classes, less of an issue for yours. For example if it was a DV visa - those are capped and highly dynamic, it can take the VO a while to ensure they’ve got the numbers right at that time of the year before releasing more. At some point those visas run out, and when it gets closer to the cap they have to be very calculated.
Edit: I should clarify that when I said a visa must be available I meant “available at the consulate for immediate use”. Some visas like IR1 are available with no caps, but they’re not available for immediate use at the consulate until the VO releases them to the consulate - hope that makes sense.
