Pasi scoring

[Fred]

I was just hoping there might be some piccies somewhere to put things in context..  

Sorry not that I know of.

By what I can work out from the PASI different people will score the same person in different ways. It's too difficult to fully understand in my opinion.

I go to a training hospital and I have seen two students give different scores to the dermatologist. I suppose if you keep doing the training it gets more precise but I'm not convinced. I've tried many time to complete the training and understand it, but I always end up with a different score.
