Now, this is just me, but my viewing for the majority of the time is in the 200's and a few in the 300's none in the 400's or 500's (I'm not a big movie person)
600's and 700's for the sports channels and a few in the 800's for a few music channels ...
Now I could pair the 300's down to about maybe 5 tops, just my local RSN in the 600's, in the 700's only for the NFL and MLB.
So in reality thats only about 8 channels from 300 to 800, if you only count MY teams in the 600-800 range.
So, out of the 200's I'll pair down to channels I watch as well as channels that I may watch a few times, just for the benefit of doubt.
OK, in the 200's I count 40 channels that I have watched, some only a few times a year if something happens to catch my eye, but I'll count them as well ...
So I was pretty close to my 50 channel estimate, I ended up at 48 ...
Remember that included MY Sports teams.
