Calculate RSD on alternating injections

Hello,

 

I want the be able to calculate the RSD of our reference injections, but we need to do it each time with a different injection. I'm out of inspiration to get them grouped together. This is the situation:

 

1) at the beginning of the sequence, the reference is injected 5 times

2) after 4 sample injections the reference is repeated

3) in total this are 6 reference injections, RSD needs to be calculated on those

 

So far no problem, but we can build the sequence endlessly with sample injections. So if we have 8 sample injections, another reference injection is made. Then we need to calculate RSD of this reference injection with the 5 injections at the beginning, but without the reference injection made after 4 sample injection.

 

And so on for more sample injections. I don't know how to group every time the first 5 reference injections, with each other reference injection sepperately.

 

Thanks in advance,

Davy
