Correct, we nee to take into account that different countries use 
different delimiters in numbers and place corresponding wording near a 
table with statistics.

I am wondering what version of LDV Tools and LDV Analytics Center do you 
use? It looks that you need to update them up to 0.5 and 0.09 
correspondingly, since in LDV Tools v0.5 we have considerably changed 
resource consumption measurement mechanism 
(http://linuxtesting.org/20-02-2014). For instance, I see statics like 
in the picture attached. Please read carefully changes to INSTALL file 
in v0.5!

As for your questions, the old way of resource consumption measurement 
was very "hand-made" and thus wasn't accurate by its nature. That was a 
primary reason to switch to commonly used Linux control groups.
