 I second that. Richard C says it's a 'material fact' but I don't recall seeing anything to support his statement. 
Years ago capacity on the VM network was an issue but that was before DOCSIS 3 and the major upgrades we've seen since, including the move to Mpeg 4 compression.
There are also some local 'capacity' issues where a street cabinet is oversubscribed.
If Spiderplant says there's no capacity constraint, there's no capacity constraint - he knows his stuff. 
I don't think a 'Frequency Plan' would reveal much to us laymen.
