10/4, MR8.
However by the rant of some guys, your points 1 + 3 were insinuated, thus my remark.
Only reflection to your remarks:
You sort of connect lack of experience to smooth operation. That would not be a problem, beeing still safe. This lack however may very suddenly turn into point 1. Then point 2 applies, definitely, or you run out of credibility and professionalism. If point 3 then appears, a report is stringent, in the name of safety.
