Did I say permanently? No I don't think so.
Well you most CERTAINLY implied it KB. When you use the phrase "Lost 40% of their audience" it implies that 40% is gone forever and not coming back, that those people who stopped watching have officially left TNA's "audience" (or weekly viewership), which is an incredibly shoddy way of looking at things.
Not bad at all, but if that's your highest rating, that's the standard you've set.
But it's not the average (or mean) that you've set, is it? The mean is a MUCH more reliable number to determine the size of TNA's viewership, this isn't really refutable, this is simple statistics and math here. Comparing the mean rating they scored before Hogan/Bischoff to now and you'll see it's nowhere near a 40% drop in their audience like you're suggesting. You're being hyperbolic.
Going below that is failing. But wait. It's TNA so the standards are different and a .9 is a great rating right?
...No, a .9 isn't great, but YES TNA does indeed have different standards KB, different than those you'd use to judge the WWE by. Not sure how you could even argue that when comparing the size and worldwide popularity of the WWE to TNA.
Even though the situation was the same last week with the hour lead in and their ratings were way down, it's still a success right?
Who said it was a success? Not me.
