Seven v Nine News Ratings Comparisons

I don’t know if it’s too late to ask this, but , at the end of the year, I would be interested to know if 10’s ratings have improved at 5pm- at the expense of Nine- since returning the bulletin to Adelaide. I would think that having more competition from a similar product at 5pm would mean a weaker lead-in for Nine’s 6pm news and potentially explain some of the YoY decline.
