I'm pretty sure also but you already gave me a very good tip hereunder :-)

Great! I didn't realized MRTG was written in Perl. 

Actually, I think I'll have to modify function "log2rrd" in file 
MRTG_lib.pm:

        sub log2rrd ($$$) {
            ...
            my @steps = qw(300 1800 7200 86400);
            my %sizes = ( 300 => 600, 1800 => 700, 7200 => 775, 86400 => 
797);
            ...

Am I dreaming? Could it be so simple? :-)

Thanks Alex
