What do you consider a sample to mean during an EICR

We had a third 2391 test rig installed last year. Sparky was keen to please and left a very tidy job indeed. Four subsequent class assessments have now brought it to a state where Sparky would need a re-visit to address what he might see as a bit of a shambles! 
I would be more inclined to minimise dismantling and carry out fundamental tests without disconnecting where possible. A review of my own EICRs stretching back years will reinforce the point that the emphasis should be squarely on inspection with testing only a supplementary consideration. The vast majority of serious issues were uncovered by inspection. Those serious issues revealed by testing were largely by means where disconnecting was not required although, admittedly, there were quite a few open RFCs over the years. 
Trying to impose a globally accepted sample set is perhaps a handy tool for the bean counters but every job should be subject to a detailed risk assessment before arriving at a determination on sample size. That is easy for me to say but I appreciate that it would be horrendously difficult to implement in reality. 
My approach has always been to attempt to arrive at a reasonable assessment of the condition of the electrical installation by minimal disruption and as such I set my own sample sizes. The key thing is that I believe I can justify them.

I am a bit disappointed that the test rigs are a bit worn Lyle, careful reassembly is very necessary!
