Mmmm, I see what you mean, then does it mean that in the following
creation 

rrdtool create test.rrd
	DS:myvalues:COUNTER:600:U:U
	RRA:AVERAGE:0.5:1:27360		## 95 days
*	RRA:AVERAGE:0.5:6:336		## 7 days
*	RRA:AVERAGE:0.5:24:372		## 31 days
	RRA:AVERAGE:0.5:288:365		## 365 days
*	RRA:MIN:0.5:1:27360		## 95 days
	RRA:MIN:0.5:6:336		## 7 days
	RRA:MIN:0.5:24:372		## 31 days
	RRA:MIN:0.5:288:365		## 365 days
*	RRA:MAX:0.5:1:27360		## 95 days
	RRA:MAX:0.5:6:336		## 7 days
	RRA:MAX:0.5:24:372		## 31 days
	RRA:MAX:0.5:288:365		## 365 days

the lines with the '*' are redundant ?

-K.
