The THX 35FtL Standard

THX changed the standard from 30 to 35FtL because of customer complaints if I remember THX training correctly, but where did 30FtL originate and why?
Doesn’t this have more to with screen size, viewing distance, and total light? My 32″ LG LCD viewed from 8 feet looks good at 35FtL as does my 51″ Samsung Plasma viewed on average from 13 feet. However, my 75″ Mitsubishi LaserVue is outputting 21FtL and at a 10 foot viewing distance I would not want more. Then there is the standard for 14-16FtL with front projectors and in an appropriately darkened environment this too is plenty of light.
Should there be a chart somewhat like the screen size/viewing distance charts?
