reporting pooled results with unknown number of samples

HI there,

I'm looking to report pooled precision from sequences but do not know how many samples wil be run.

The sequence takes the format:

inj/vial
Blank1
CAL 1-61
Precision (Cal 3)6
Sample 1-51
Precision 2 (Cal 3)1
Sample 6-101
Precision 3 (Cal 3)1
Sample 10-131
Final Precision 4 (Cal 3)1

 

The first set of precision data uses 6 replicate injections then after every 5 samples there is a single injection of the same cal standard and the data is combined with the Precision data from the 6 injections and the pooled RSD is then also reported. The problem is I don't know how many samples ie. how many individual precision injections (after every 5 samples) will take place in the sequence and can't think how to set the report up to take this into account.

If you are able to suggest a way to approach this it would be much appreciated.

Many thanks
