Ah, that's good to know! Most hosters aren't editing older posts once the new one goes up, so if one is missing in the previous tally it's mostly an oversight.
No worries then, I don't mind not being in on one day anyway except on the final tally.
I'm doing it differently myself; I'm doing the tally in a textfile with paste & copy which I edit once or twice daily, and then copy the whole into the next post. Once that one is up I don't edit the older one anymore as that's too much prone to errors; also because sylvanwitch is usually adding her own tally later, to avoid accidentally editing the post at the same time.
