nct

My car is due its NCT on Wednesday morning. I had a look at the NCT website and they publish their test stats, showing how many tests took place and the pass rate. What I found really interesting was that it doesn't change from one year to the next. Take a look at the graph I did comparing their data and the consistency between years:

I have about exactly 51% chance of passing first time. If I fail, I will have about exactly 90% chance of passing.
It will be interesting on Wednesday if I am in the lucky 51% or the unlucky 48% (±1%)
