Alexander, your solution works perfectly.
Again, many thanks for your efforts.
My knowledge of gnuplot is not as deep as yours.

I'll post to the list as the topic is closed.

Solution:

set datafile missing NaN
y=NaN
plot	file1 every 4::0 using 1 title "rr25" ls 1, \
	file1 every 4::1 using 1 title "rr50" ls 3, \
	file1 every 4::2 using 1 title "rr75" ls 5, \
	file1 every 4::3 using 1 title "rr100" ls 7, \
	file1 using (($0-3)/4):(int($0)%4 == 0 ? (y=$1) : int($0)%4 == 3 ? $1/y 
: NaN) title "rr100/rr25" ls 9
