[HMM I OFF TOURNAMENT] "Company"

I have a question! Should I send the save file after completing the first map, or how does it work? Then, complete the second map and send it after the 2nd map, and so on, until the 9th map, or send the save file after completing the last, 9th map. And for each of the 9 maps, I need to make daily save files, is that correct?

And in the first map, should I save the game before taking the city, or after (when it saves automatically)?
