I sort of did here:
"Your mileage may vary Thats real world useage on my TiVo. Its 7% full so just multiplied the recorded hours by 100 and divided by 7, after converting all the hd recordings to sd by x by 4. And then dividing the sd recordings by 4 to double check.
Its as accurate a figure without getting to complicated. My ratio of sd to hd recordings are 1:2. So the HD figure will be more accurate than the SD.

I thought it was implicit that the bitrate was altering so its as accurate without getting more complicated. The more complicated bit would be taking much more samples to eliminate as much as possible differences in bitrate between channels programs and sd/hd.
I do intend to do this to get a more accurate estimate over time.
