percentages using break-sums

Hi,

I tried calculating rowlevel percentages of a total of a break wich 
should show a result like:

#      %
3     75        
1     25
_
4

using:

<Variable name="sumnumber" value="val(q.number)" type="sum" 
resetonbreak="Maand" precalculate="yes"/>
<Variable name="sumturnaround" value="val(q.turnaround)" type="sum" 
resetonbreak="Maand" precalculate="yes"/>
<Variable name="perc_number" value="(val(q.numberl)/v.sumaantal)*100" 
type="expression" resetonbreak="Maand" />
<Variable name="perc_turnaround" 
value="(val(q.turnaround)/v.sumturnaround)*100" type="expression" 
resetonbreak="Maand" />

and showing them (q being the main query):

<field value="q.aantal" width="10" align="right" col="3"/>
<field value="val(q.turnaround)/100" width="10" align="right" 
format="'!# %.02f'" col="5"/>
<field value="v.perc_number" width="10" align="right" format="'!# 
%.01f'" col="6" />
<field value="v.perc_turnaround" width="10" align="right" format="'!# 
%.01f'" col="7" />

But see percentages > 100%...
As precalculate and delayed are not documented I'm kind of guessing and 
experimenting ;)

Can this be done with RLIB and if so how should it be done..
