At the end of parshat Pinchas, the korbanot for sukkot are mentioned, and since there is a slight difference between each day, they are repeated eight times. My issue is that if you look at the way it is written in the Torah, all the odd days begin with one word on the first line, and all the even days begin with three words. My question is why?
I think this is just an "anomaly" in your Tikkun! The only requirement is that all these parshiot are stumot, meaning that there must be a minimum of (I think) 9 letter yod's from the end of one parsha to the beginning of the next one.
Considering that within these 8 parshiot, the number of words are almost identical, it seems very likely that you would find a pattern repetition occurring.
As a matter of fact, look at this scanned page from the "old fashioned standard Blue Tikkun" (I don't recall the author, offhand.) You'll see no definitive pattern at all other than their all being stumot.
Compare your Tikkun with a few Sifrei Torah. I'll wager that it is somewhat different in each Torah. (Unfortunately, my camera won't work tomorrow, otherwise, I'd upload a pic for you ;-)
