This seems o.k.

I assumed you were suffering from averaging when values are 
travelled from a high resolution RRA to a coarser RRA.

I think in this case you are suffering from another type
Of averaging. You plot more rows horizontally than your graph 
Is wide. The solution is of course to plot a wider graph then.

But if that is not a solution, you might ask yourself what you
Do want to see. The maximum in the period covered by that pixel?

If so, changing the type of the AVERAGE RRA to a MAX RRA may work.
Rrdtool dump, edit to change the RRA type and rrdtool restore
Should do it.

Serge.
