My estimate was ~270-272pp; 16 A4 sheets/m^2 == .0625m^2/sheet; * 80g/m^2 == 
5g/sheet; * 272sheets == 1.36kg!

Good point - but I have rarely printed anything large enough to benefit from 
duplex in the last decade - I used to print 4 pages/sheet at home using various 
imposition packages or print drivers.

Did not consider those core, but for giggles:

$ units `cat ~/tz/data/{[ef]*,*{ica,asia},back*,zone*.tab} | wc 
1.5766488 kg	#	on about ~316-319pp

$ units `grep -h '^\s*#\|^\s*$' ~/tz/data/{[ef]*,*{ica,asia},back*,zone*.tab} | 
wc -l`*12point/277mm*A4paper*80gsm
1.1474093 kg	#	on about 230-232pp

giving ~73% comment or blank lines by line or page count or weight.

I am here excluding data line comments, which would require analyzing numbers of 
characters and/or areas occupied on the line to get comparables.

Take care. Thanks, Brian Inglis              Calgary, Alberta, Canada
