Bert,
Your calculations do not take into account the effects of using MPEG-2
coding at equal bitrates. I think you'll find the real world differences
between 1080i30 and 720p60 to be much less that 12.5%, and the macroblocking
artifacts on stressful scenes to be worse on the 1080i30 material, blowing
the viewing experience no mater how much better a subsequent static scene
looks.

It's a 12.5 percent
improvement either way you look at it.
