Doing some more math, Dory without Japan, HK, UK, and Mexico made $296 million OS. I now see Dory making about 320 OS without said territories. Dory had a sub 10% drop in Japan. If it keeps on having good drops, Dory will make about $65-70 Million in Japan. Dory had another drop over 50% in Mexico, I think it'll make $27 Million now instead of $30. Hong Kong, Dory will likely end with $6.2-$6.5 Million. UK, Dory made $10.8 million dollars without previews. Since Dory has little competition, I can see it legging it to $55-60 million. In Germany and Italy it'll make about $35 million combined if it follows TS3 and MU, if it follows IO it'll make $45-50 million. In the other territories left, Dory should make about an extra $21 million if it copies Inside Out.
Edit 1: After further research on Nemo's BO in Germany, I now see it doing anywhere from $40M to $70M.
Worst Case: 490+320+65+27+6.5+55+21+57=$1,042 billion
Middle: $1,055 billion
Best: $1,070 to 1,075 billion
My Prediction: $1,060 billion
