The body says "quoted-printable" but the headers say

This is probably why I am seeing all those <equal><20> where you
want me to see a space ?

Either the list or your mail client did something wrong here.

If one RRA contains these 5-minute maxima (two sets)

ds0:  1 2 3 4 5 6 1 2 3 4 5 6 1 2 3
ds1:  5 4 3 2 1 0 1 2 3 4 3 2 1 0 0

these are consolidated into the following 15-minutes maxima:

ds0:    3     6     3     6     3  
ds1:    5     2     3     4     1

When I try your adding: CDEF:G=3Da,c,h,j,l,n,p,r,t,v,x,+,+,+,+,+,+,+,+,+,+ \

I get:

ds0:  1 2 3 4 5 6 1 2 3 4 5 6 1 2 3
ds0:  5 4 3 2 1 0 1 2 3 4 3 2 1 0 0

sum:  6 6 6 6 6 6 2 4 6 8 8 8 2 2 3    <-- maximum 8


ds0:    3     6     3     6     3  
ds1:    5     2     3     4     1

sum:    8     8     6    10     4      <-- maximum 10

Maybe you don't have this exact setup and maybe you don't even have
more than one RRA for each of (MIN,AVERAGE,MAX).  Still, rrdtool may
need to do consolidation because of the image width.
